What is the product in the reaction below? OHSOCI2 SOCl2- socz pyridine B. Cl C. D. SH A. S-C A) B B) C c) D D) AExplanation / Answer
1. which of the following has a trigonal planar structure?
a. CH3-, b. CH3+, c. NH3, d. BF3, e. OH3+
ANSWER: (B) b and d
a. CH3-, No of sigma bonds = 3, no of lone pairs on central atom =1, so hybridization = 3+1 = 4 means sp3,
so shape is tetrahedron or triangular pyramid
b. CH3+, No of sigma bonds = 3, no of lone pairs on central atom =0, so hybridization = 3+0 = 3 means sp2,
so shape is triangular
c. NH3, No of sigma bonds = 3, no of lone pairs on central atom =1, so hybridization = 3+1 = 4 means sp3,
so shape is tetrahedron or triangular pyramid
d. BF3, No of sigma bonds = 3, no of lone pairs on central atom =0, so hybridization = 3+0 = 3 means sp2,
so shape is triangular
e. OH3+, No of sigma bonds = 3, no of lone pairs on central atom =1, so hybridization = 3+1 = 4 means sp3,
so shape is tetrahedron or triangular pyramid
2.Aswer: A, B, C, D, E All are correct
Alcohol can be Lowry acid as it has H bonded to O and Lewis base as it has O which can donate electrons. Similarly for amines are Lowry bases as they can accept protons by the electronegative N atom.
3. Answer is (A) B cyclohexyl chloride
cyclohexanol + SOCl2 (pyridine) -> cyclohexyl chloride + SO2 + pyridine.HCl
