FAQS on 2 bromonaphthalene
Q: What is the chemical structure of 2-bromonaphthalene?
A: 2-bromonaphthalene has a naphthalene ring (two fused benzene rings) with a bromine atom attached to the second carbon. Its molecular formula is C₁₀H₇Br, and it is commonly used in organic synthesis and pharmaceuticals.
Q: How is 2-bromonaphthalene synthesized?
A: It is typically synthesized via electrophilic aromatic substitution, where bromine replaces a hydrogen atom on naphthalene. Catalysts like iron or aluminum bromide are often used to facilitate the reaction.
Q: What is the sodium diacetate formula and its primary use?
A: The sodium diacetate formula is C₄H₇NaO₄. It is a sodium salt of acetic acid, widely used as a food preservative and antimicrobial agent, particularly in baked goods and meats.
Q: Are 2-bromonaphthalene and sodium diacetate used together in reactions?
A: Generally, no. 2-bromonaphthalene is a halogenated aromatic compound for synthesis, while sodium diacetate is a preservative. They serve distinct roles in different industrial or chemical contexts.
Q: Is sodium diacetate safe for consumption?
A: Yes, sodium diacetate is recognized as safe (GRAS) by regulatory agencies when used within recommended limits. It inhibits mold and bacterial growth in food products without significant health risks.
