Which compounds are isomers of each other? a. methanol and methanal b. propanoic acid and pentanoic acid c.1-propanol and 2-propanol d.1-chloropropane and 2-bromopropane?

The correct answer is option c.

Explanation:

Isomers are defined as those molecules which have same molecular formula  and have different structural formula. They all have same molecular weight  and same number of atoms  but they have differ in boiling points.

In 1-propanol and 2-propanol number of carbon atoms same, number of hydrogen atoms same and number of oxygen atom are same.Only difference is in position of (-OH) group in both the molecules.

Hence, the correct answer is option c.

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.

⇌(double head arrow) means reversible reaction).
