Question

The compound which contains both ionic and covalent bonds is
(1) CH4
(2) H
(3) KCN
(4) KCI​

Answer 1

Answer:

(3) KCN

Explanation:

First of all let's know what are ionic and covalent bonds.

Ionic bonds - The bonds which formed between the ions by the loss or gain of electrons are called ionic bonds.

For example, KCl

In this, K (potassium) losses one electron and Cl (chlorine) gains that one electron forming the given compound.

Covalent bonds - Those bonds which are formed by the sharing of electron pairs are called covalent bonds .

For example, CH4

In this, C (carbon) and 4 H (hydrogen) share electron pair to form the covalent bond.

So according to this,

option (1) and (4) are eliminated.

Now coming to option (2) ,

H (Hydrogen) is simply an atom, which forms no bond in free state .

So we have correct option is (3)KCN

In KCN, both covalent and Ionic bond is formed, that means Coordinate Bond or dative bond is formed.
