Question

truefalseThere are four ? bonds in this molecule.

truefalseThere are three lone pairs of electrons in the complete Lewis structure.

truefalseThere are eleven ? bonds in this molecule.

truefalseThe C-N bond is formed from overlap of an sp3hybrid orbital from the carbon atom with an sp2hybrid orbital from the nitrogen atom.

truefalseAn sp2hybrid orbital on C-1 overlaps with an sp3hybrid orbital on C-2 to form the sigma bond between C-1 and C-2.

truefalseThe ? bond between C-3 and O is formed by overlap of unhybridized p atomic orbitals.

truefalseThe C-2 and C-3 atoms cannot rotate about the internuclear axis between the two atoms since the ? bond would break.
