NCERT Solution: Carbon and its Compounds
The two features of carbon that give rise to a large number of compounds are as follows:
→ Catenation – It is the ability to form bonds with other atoms of carbon.
→ Tetravalency – With the valency of four, carbon is capable of bonding with four other atoms.
The formula for cyclopentane is C5H10. Its electron dot structure is given
below.

(iv)
(i) Bromoethane
(ii) Methanal (formaldehyde)
(iii) Hexyne
(ii) Methanal (formaldehyde)
(iii) Hexyne
CH3CH2OH + (Alkaline KMnO4) → CH3COOH
Since, in this reaction one oxygen is added to ethanol, hence it is an oxidation reaction.
