H₂O < H₂S < BF₃

Answer

BF₃ < H₂O < H₂S

Question 10

Which of the following is non-polar?

Accepted Answer

CO2

Answer

SO2

Answer

H2O

Answer

NH3

Question 11

Although F is more electronegative than H, the resultant dipole moment of NH₃is much more than that of NF₃. It can be explained as

Accepted Answer

the lone pair of nitrogen opposes the dipole moment of NF₃ while it is added to the dipole moment of NH₃

Answer

all the dipoles of NF₃ are in same direction

Answer

all the dipoles of NH₃ are in opposite direction

Answer

NH₃ has a regular geometry while NF₃ has irregular geometry which makes dipole moment of NH₃ more than NF₃.
