Question

which of the following molecules doesn't sp3hybridisation?
(CH4,BF3,NH3,H2O)​

Answer 1

Answer:BF3 doesn't have sp3 hybridization..it is sp2 hybridised.

Explanation:

Answer 2

$BF_3$ does not have $sp^3$ hybridization.

• The valance shell electron of C is 4. Thus total electron is 4+4=8.
• The total electron pair is 8/2=4.
• Thus total bond pair is 4. So, $CH_4$ have $sp^3$ hybridization.
• The valance shell electron of B is 3. Thus total electron is 3+3=6.
• The total electron pair is 6/2=3.
• Thus total bond pair is 3. So, $BF_3$ have $sp^2$ hybridization.
• The valance shell electron of N is 5. Thus total electron is 5+3=8.
• The total electron pair is 8/2=4.
• Thus total bond pair is 4. So, $NH_3$ have $sp^3$ hybridization.
• The valance shell electron of O is 6. Thus total electron is 6+2=8.
• The total electron pair is 8/2=4.
• Thus total bond pair is 4. So, $H_2O$ have $sp^3$ hybridization.
