Ques:Information:  - A cyclic compound ("ring compound") is a term for a compound in the field of chemistry in which one or more series of atoms in the compound is connected to form a ring. Rings may vary in size from three to many atoms, and include examples where all the atoms are carbon (i.e., are carbocycles), none of the atoms are carbon (inorganic cyclic compounds), or where both carbon and non-carbon atoms are present (heterocyclic compounds). Depending on the ring size, the bond order of the individual links between ring atoms, and their arrangements within the rings, carbocyclic and heterocyclic compounds may be aromatic or non-aromatic, in the latter case, they may vary from being fully saturated to having varying numbers of multiple bonds between the ring atoms. Because of the tremendous diversity allowed, in combination, by the valences of common atoms and their ability to form rings, the number of possible cyclic structures, even of small size (e.g., <17 total atoms) numbers in the many billions.   - Dihydrothiophene is a heterocyclic compound .  - Substitution reaction (also known as single displacement reaction or single replacement reaction) is a chemical reaction during which one functional group in a chemical compound is replaced by another functional group. Substitution reactions are of prime importance in organic chemistry. Substitution reactions in organic chemistry are classified either as electrophilic or nucleophilic depending upon the reagent involved. There are other classifications as well that are mentioned below.  - Organic chemistry is a chemistry subdiscipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure includes many physical and chemical methods to determine the chemical composition and the chemical constitution of organic compounds and materials. Study of properties includes both physical properties and chemical properties, and uses similar methods as well as methods to evaluate chemical reactivity, with the aim to understand the behavior of the organic matter in its pure form (when possible), but also in solutions, mixtures, and fabricated forms. The study of organic reactions includes probing their scope through use in preparation of target compounds (e.g., natural products, drugs, polymers, etc.) by chemical synthesis, as well as the focused study of the reactivities of individual organic molecules, both in the laboratory and via theoretical (in silico) study.  - Thiophene, also commonly called thiofuran, is a heterocyclic compound with the formula CHS. Consisting of a flat five-membered ring, it is aromatic as indicated by its extensive substitution reactions. Related to thiophene are benzothiophene and dibenzothiophene, containing the thiophene ring fused with one and two benzene rings, respectively. Compounds analogous to thiophene include furan (CHO) and pyrrole (CHNH).  - A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles.

Ques:Information:  - The Military William Order, or often named Military Order of William (Dutch: Militaire Willems-Orde, abbreviation: MWO), is the oldest and highest honour of the Kingdom of the Netherlands. The Order's motto is "Voor Moed, Beleid en Trouw" (For Bravery, Leadership and Loyalty). The chivalric order was established on 30 April 1815 by King William I and was presented for feats of excellent bravery on the battlefield and as a meritorious decoration to senior military officers. Comparable with the French Légion dHonneur but far less awarded, the Military William Order is a chivalry order of merit open to everyone regardless of rank and nobility, and not only to Dutch military but also foreigners. To date the Order is extremely rarely awarded and only for excellent bravery in battle.  - Jacob Pieter van Helsdingen ( 7 March 1907 -- 7 March 1942 ) was a pilot of the Royal Netherlands East Indies Army Air Force . Jacob and August Deibel were the most successful Dutch pilots on the Brewster F2A fighter . He was twice awarded the Military William Order for bravery in battle .  - 1st Lieutenant August Gerard Deibel (11 September 1915  12 June 1951) was a Dutch pilot of the Royal Netherlands East Indies Army Air Force. He was part of 2-VLG-V, which was stationed in Singapore before its withdrawal to Java. His unit emblem was a rhinoceros head painted on both sides of the front fuselage on his Brewster Buffalo aircraft. His rank and surname, 'Lt Deibel' was printed beside the nose art.  - Singapore, officially the Republic of Singapore, and often referred to as the "Lion City" or the "Little Red Dot", is a sovereign city-state in Southeast Asia, and the world's only island city-state. It lies one degree (137 km) north of the equator, south of the southernmost tip of continental Asia and peninsular Malaysia, with Indonesia's Riau Islands to the south. Singapore's territory consists of a diamond-shaped main island along with 62 other islets. Since independence, extensive land reclamation has increased its total size by 23% (130 km), and its greening policy has covered the densely populated island with tropical flora, parks and gardens.  - Java (Indonesian: Jawa; Javanese: ; Sundanese: ) is an island of Indonesia. With a population of over 141 million (the island itself) or 145 million (the administrative region) Census released in December 2015, Java is home to 56.7 percent of the Indonesian population and is the most populous island on Earth. The Indonesian capital city, Jakarta, is located on western Java. Much of Indonesian history took place on Java. It was the center of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally.

Choices: - 2015  - military order of william  - red dot

Ans:
military order of william
