Which of the following molecules would be nonpolar?

Question

a) N2O

b) s****. />
c) CO2

d) H2O

e) HCCL3

the answer is CO2 but why please explain...will give 5 pts to best answer thanks

Answer 1

because only CO2 has a linear bond angle

O=C=O, hence the polarities on both sides cancel each other making the total polarity zero. Hence, the non-polarity

Answer 2

CO2 is a symmetrical molecule; C in the middle and an O on each side, with all 3 atoms in a straight line, so the polarities of each CO bond cancel out.  By way of comparison, H2O is an H flanked by two Os, but they're not in a straight line, so the H is +ve and the opposite end of the molecule is -ve.  Similarly N2O.  SCO is a C flanked by S and O, and O is more electronegative than S.  In HCCl3, you've got a C surrounded by 3 Cls and an H.  H is more electropositive than the Cls.

Answer 3

Yes, the answer is CO2 because it is linear.....all others are bent which gives u a dipole......it's suppose to be 10 points not 5, thanks.

Answer 4

c) O=C=O Il is linear
