3
2.
(a) sp
(b) sp?
(d) sp?
(c) sp
Answers
It has 3 bond pairs and one lone pair, which is responsible for negative charge. Every bond pair shares two electrons between the bonding atoms and lone pair consists of two unshared electrons. So totally it have 6 shared electrons and 2 unshared electrons around the carbanion. Thus it has sp3 hybridization and pyramidal geometry.
Hybridisation of the negatively charged carbon atom in acarbanion. Given the carbanion, R X 3 C X − ,
the carbon is sp3 hybridized, unless it is participating in resonance. This is clear from its steric number.
Why do some carbanions have sp2 hybridisation? Is it because of special conditions or presence of a group (I know they are conjugated and perform resonance but why do they have sp2 hyb in the first place)?
How many pair of electrons are around the carbon atom in carbanions?
If a negative charge is created on carbon in a cyclic ring, does the hybridisation status of the carbon change, and if this does happen, why?
Why is carbocation sp2 hybridized?
Why are carbocation and carbanion considered as sp2?
What is the hybridization state of carbon in carbocations?
Why is a carbocation SP 2 hybridised?
What is the hybridization of the carbon with a positive charge in phenyl carbocation, and why?
Which is more stable carbanion: cyclopentadienyl or benzyl carbanion?
What is the hybridization of Carbon in CH2=CH–(-) C:H2? The last carbon has an electron pair and also a negative charge.
