Identify the correct statements from the following. (1) The dipole moment of \(\mathrm{CO}_2\) and \(\mathrm{BF}_3\) is zero. (2) The dipole moment of \(\mathrm{NF}_3\) is higher than the dipole moment of \(\mathrm{NH}_3\). (3) The dipole moment of \(\mathrm{HI}\) is lower than the dipole moment of \(\mathrm{HCl}\).
- A 1,3
- B 1,2
- C 2,3
- D \(1,2,3\)
Answer & Solution
Correct Answer
(A) 1,3
Step-by-step Solution
Detailed explanation
1 . The \(\mathrm{BF}_3\) molecule has a symmetrical trigonal planar geometry, the moment of any two B-F dipoles is equal in magnitude but opposite in direction to the moment of the \(\mathrm{BF}_3\) molecule is zero. Same as \(\mathrm{CO}_2\). 2. In…
