Photochemical isomerization of (E, E)-2,4-hexadiene to (Z, E)-2,4-hexadiene is a two-step process in which a photochemically driven intermediate forms and then thermally rearranges to give the product. Draw the structure of this intermediate, using wedge-and-dash bonds to denote the appropriate stereochemistry.

Its response to this question is as follows:

Explanation:

Please find in the attachment file the complete query and the answer file.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
