Which of the following statements is/are correct ?      
  • a)
    Out of trimethylamine and trimethylphosphine, trimethylamine has higher dipole moment ?
  • b)
    Out of (SiH3)2O and (CH3)2O, (SiH3)2O is more basic. 
  • c)
    C–C bond length (in pm) in C2 molecule is greater than O–O bond length in O2 molecule.
  • d)
    N(SiMe3)3 and BF3 molecules are isostructural.
Correct answer is option 'A,C,D'. Can you explain this answer?

Which of the following statements is/are correct ? a)Out of trimethyl...
(A) Nitrogen is more electronegative than phosphorus.
So, dipole moment of trimethylamine is greater than trimethy phosphine.
In trisilyl ether the lone pair of electron on oxygen atom is less easily available for donation because of pπ-dπ
delocalisation due to presence of the vacant d-orbital with Si. This however is not possible with carbon in CH3–O–CH3 due to the absence of d-orbital making it more basic.
(C) Bond order of C2
and O2 are same i.e., 2. In C2 molecules both bonds are π-bonds whereas, there is one  σ and one π-bond in O2 molecule
C2 = 131 pm ; O2 = 121 pm.

Which of the following statements is/are correct ? a)Out of trimethyl...
A) The correct statement is: Out of trimethylamine and trimethylphosphine, trimethylamine has a higher dipole moment. This is because trimethylamine has a nitrogen atom with a lone pair of electrons, which contributes to a greater dipole moment compared to trimethylphosphine.

b) The correct statement is: Out of (SiH3)2O and (CH3)2O, (SiH3)2O is more basic. This is because the presence of the electronegative silicon atom in (SiH3)2O makes the oxygen atom more basic compared to the oxygen atom in (CH3)2O.

c) The statement "C" is missing in the question. Please provide the complete statement for evaluation.
