Question

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?

Answer 1

Answer:The correct answer is option c.

Step-by-step 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 2

Answer is: c.1-propanol and 2-propanol.

1-propanol and 2-propanol are both alcohols and have same number carbon, hydrogen and oxygen atoms.
a) methanol is alcohol and methanal is aldehyde.
b) propanoic acid and pentanoic acid are both carboxylic acids, but had different number of carbon, hydrogen and oxygen atoms..
d) 1-chloropropane and 2-bromopropane have different substituent (chloro and bromo).
