Answer 2

Answer with Explanation:

(i)Coavlent bond: It is that type of bond which formed by sharing of electrons between two bonded atoms.

The formula of ethane is $C_2H_6$.Ethan is covalent compound because ethane is formed by sharing of electrons between H and C.

(ii)

Catenation: It is self combining property of element .

Carbon has the property of self combining.Therefore, it shows the property of catenation.

(iii)Acetic acid which contains a very low amount of water (less than 1%) is called anhydrous (water-free) acetic acid or glacial acetic acid. it solidifies into solid acetic acid crystals just cooler than room temperature at 16.7 °C.That is why ethanoic acid is called glacial acetic acid.
