Q:Alcohols and carboxylic acids in the hydroxyl group, the oxygen atoms are sp3 hybrid or sp2 hybrid

In the carbonyl R-COOH carbon, one of the O can only form a double bond with C, that is, a sigma bond and a Pi bond, and also with R and OH each form a sigma key, a total of four keys, C on the most The outer layer and no electrons to form solitary electrons. According to the principle of hybrid, because there are only three sigma, need to participate in the hybrid track can only be three, that is, sp2 hybrid.

Q:Carboxylic acid in the end can not react with the new copper hydroxide

But the formula is written in the carboxylic acid, because the reaction of aldehydes with the new copper hydroxide is alkaline conditions, the carboxylic acid is not present, but the carboxylic acid and alkali, copper hydroxide, copper oxide are reaction, Side reactions too much, too complex, in order to show that the reaction principle, simply from the simple processing, directly write carboxylic acid

Q:The role of sugar in the human body?

Toxicity: Carbohydrate is the main source of heat, each carbohydrate can provide 4 kcal of calories. Carbohydrates in the exercise after oxidation, the final product for the carbon dioxide and water, the body without any harm.
