Question

4. The hybridisation in PF3 is A. sp3 B. sp2 C. dsp3 D. d2 sp3

Answer 1

Answer:

Explanation:

Correct answer is sp3

Answer 2

Answer:

(a) sp3

Explanation:

valance shell ele- in P = 5

  "            "      "     in 3F = 7x3= 21

                                               = 26

in this molecular formula [H] is absent,

so,                                        = 26/8= 3 + 2electron, & we know that 2 electron = 1 Loan pair

So. we get steric no. 4 so here hybridisation occurs sp3
