Chemical Bonding
$$BF_{3}$$ forms an adduct with $$NH_{3}$$ because:
In co-ordinate bonds, the acceptor atoms must essentially contain in its valency shell an orbitial:
Co-ordinate bond is formed when an atom with lone pair donates it to an atom with a vacant orbital, orbital with no electrons.
$$BF_{3}$$ forms an adduct with $$NH_{3}$$ because:
PF$$_{3}$$ can act as a donor molecule while NF$$_{3}$$ shows little tendency to act as a donor. This is because in PF$$_{3}$$, lone-pair on P is easily donated compared to that of N.
Which of the following can act as Lewis acid?
Which of the following molecule is not hypovalent
Which of the following does not contain any coordinate bond?
Which one of the following does not have a pyramidal shape?
Which of the following does not contain any coordinate bond?
Explain the following on the basis of valence bond theory: $$BF_{3}$$ is planar but $$NH_{3}$$ is not.
$$BF_3$$ has less lewis acidic property than $$BBr_3$$ . Why ?
$$(CH_3)_3$$ COH is less acid than $$(CH_3)_3$$ SiOH. Why ?
