Question

predict the hybridisation and shapes of few molecules and ions??​

Answer 1

Answer:

(i) In BCl

3

, Boron is sp

2

hybridized and thus, the shape of BCl

3

is trigonal planar. (figure 1).

(ii) The shape of CH

4

is tetrahedral, carbon is sp

3

hybridized. (figure 2)

(iii) The shape of NH

3

molecule is pyramidal, the nitrogen atom is sp

3

hybridized but lone pair on N gives pyramidal shape. (figure 3)

(iv)The shape of CO

2

is linear because there are no lone pairs affecting the orientation of the molecule. and having hybridization is sp

2

.

O=C=O

Answer 2

Answer:

Explanation:

Use the valence concept to arrive at this structure. Concentrate on the electron pairs and other atoms linked directly to the concerned atom. This step is crucial and one can directly get the state of hybridization and shape by looking at the Lewis structure after practicing with few molecules.
