MCQ
What is the expected geometry of CH3 - NH - CH3?
- ASquare planar
- BTrigonal planar
- CTrigonal pyramidal
- DTrigonal bipyramidal
Explanation:
CH3 - NH - CH3 is an amine in which two hydrogen atoms are replaced by methyl groups.
The hybridisation of N atom of amines is same as that of ammonia, and is also expected to have a pyramidal geometry, with N at the apex and the groups CH3, H and CH3 occupying the corners of a trigonal base.

Given : $\log 3=0.48$
$A.$ Reaction completes in $1000\,s$.
$B.$ The reaction has a half-life of $500\, s$.
$C.$ The time required for $10\, \%$ completion is 25 times the time required for $90 \,\%$ completion.
$D.$ The degree of dissociation is equal to $\left(1-e^{-k t}\right)$.
$E.$ The rate and the rate constant have the same unit.
