Conjugated dienes interact with compounds containing double bonds to produce six-member cyclic compounds that are commonly used in organic synthesis. For example, compounds may undergo the following reactions:

(4) formula for 4 H 4 C O (polymer) compounds (1) the formulas for the I _____, 1 mol, which complete combustion takes ________mol O 2 (2) the reaction of chemical equation for __________________________________________ (3) is polycondensation reaction, the structure of the compound short form for _____ (4) under certain conditions, compound, and compounds

Can produce A similar reaction in the reaction, the two compounds (are isomers), short form the structure of the two compounds were _____ _____ about compounds (5) the following is true of A _____ A (fill in the letter).

Belongs to aromatic hydrocarbon B. Both can discolor carbon tetrachloride solution of bromine C.

The addition of sufficient H 2 to the product is 3-methylpentane d. Under heating conditions can react with newly prepared Cu(OH) 2 to form a red precipitate
