Question

Reactions of Alkenes

Draw the products formed in each reaction.

Answer 1

Constitutional isomers are nothing but structural isomers having same molecular formula but different in arrangement of atoms, due to difference in arrangement of atoms there may be functional group change

If the groups attached to the carbon atoms are on same side then the compound is called as cis-isomer, if the groups are in opposite direction then the compound is said to be Trans isomer, cis and transe isomers are called sterioisomers

(a)

Let us draw the normal structure and write the molecular formula of each compound

(b)

The double bond is Trans double bond, so it is a transe isomer, the stereoisomer will be the cis isomer; let us draw the cis isomer of compound A

So the structure of stereoisomer is

(c)

Let us draw the normal structure and write the molecular formula of each compound

The compounds have same molecular formulas; the arrangement of atoms is different, hence they are constitutional isomers
