Question

(33) Which of the following molecules has a dipole moment equal to 0? A) SIH4 B) HO C) CH F2 (tetrahedral) D) CBrC12F (34) Which one of the following molecules is overall nonpolar? A) NH3 B) OF 2 C) CH2C1 D) H2O E) BeCl2

Answer 1

3u:- 4 NH3 :- tetrahedral S. WHz is the compound having geometry. It is polar. Because of Nitrogen is. more Electronegative than H. . OF, - In it produclos net dipolemoment like It is polar c) CH₂U:- No but dipole für cou C-H bonds ; This bond forms H- C-H dipole. so It ispolar D) H₂O:- in O-H bond, o 'H' has negative charge forms positive charge. It is polar It is bent -shape. So, dipole will not get canceled. E Bella :- e-Be-u It is linkar structure, 30 net dipole caused by atoms wil get Cancelled. It is non-polar] chlorine sitive - option is Correct anot h er

33: A) Situ :- Н electronegative HS: H Hydrogen is more than Si. 30, SiH i will be pulled by H'atom. silicon atom towards 4- Hydrogem , pull them. ". Net dipole moment get Canceled. • dipole moment ou B) HD It is a polar molecule with 1.85 dipole moment, CH₂ Fair Flowerine, there will be a Because Electronegativity of negative dipole on Flourine. in wet dipole moment &0. D) CBr Clef ac - BY Electronegativities of Because of differences between four different atoms attached They produce dipole moment to Single C-atom. that is not equal to zero. Net dipole moment to. . is the correct option.
