Answer 1

Explanation:

In organic chemistry, a saturated compound is one which has all single bonds in between the carbon-carbon atoms. Most of the saturated hydrocarbons are alkanes. So, the structures in which the carbon atoms are arranged in a ring are called as cycloalkanes, with a general formula of CnH₂n.

Answer 2

1-Most of the saturated hydrocarbons are alkanes. So, the structures in which the carbon atoms are arranged in a ring are called as cycloalkanes, with a general formula of CnH₂n. There are many saturated cycloalkanes. The cycloalkane with the least number of carbon atoms is - Cyclopropane with 3 carbon atoms.

2-In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. Formula of the functional group present in aldehydes is -CHO and Ketone -C=O
