Question

Which of the following molecules is not planar?
(a) BF3
(b) NH
(c) CH-
(d) CH,
The controlatoiminen hallineulee is hybridi​

Answer 1

Answer:

To find the hybridization of central atoms:

For a molecules,

8

Totalno.ofvalenceelectronsofallatoms

i.e. for BF

3

It is

8

24

=3

This obtained quotient can be called as co ordination number.

For Ions,

Co ordination number =

1

(v+x−c+a)

where, v= no. of valence electrons in central atom

x= no. of mono valent electrons around central atom

c= +ve charge on Cation

a= −ve charge on Anion

For NO

It is

(5+0−0+1)=3

Hence, According to the given table BF

3

and NO

have sp
