The stretch for a c-h bond where the carbon is sp2 hybridized would be located where on an ir spectrum? (1 pt) at approximately 3300 cm-1 just below 3000 cm-1 just above 3000 cm-1 at approximately 2700 cm-1

Just above of 3000

Explanation:

The strength of C-H bond determines the position of the C-H stretching vibration peak higher strength leads to higher wavenumber.

C atoms sp hybridized (triple bond between carbon atoms) have more sigma character in their bonds (there are less p orbitals involved), hence their bonds are stronger. The C-H stretching of sp hybridized carbon are around 3300 .

C atoms sp hybridized (single bond between carbon atoms) have less sigma character in their bonds (there are more p orbitals involved), hence their bond are weaker. The C-H stretching of C sp hybridized are around 2900 .

C atoms sp hybridized (double bond between carbon atoms) have less sigma character than sp atoms, but more sigma character than sp atoms in their bonds. Hence their bonds have intermediate strength. The C-H stretching of C sp hybridized are around 3100 .
