There are 18 constitutional isomers with the molecular formula C8H18. Without drawing all 18 isomers, determine how many of the isomers will have a parent name of heptane

Among the 18 constitutional isomers with molecular formula C₈H₁₈, there are 3 isomers with the parent name of heptane.

Explanation:

From the 18 constitutional isomers with molecular formula C₈H₁₈, 3 of the isomers will have a parent name of heptane. They are

The structures of the 3 isomers with the parent name of heptane are given in the attachment below.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
