[Co(en)(NH3)2Cl2]Cl
Assertion : The [Ni(en)3]Cl2 (en = ethylene diamine) has lower stability than [Ni(NH3)6]Cl5.
Reason : In [Ni(en)3]Cl2 the geometry of Ni is trigonal bipyramidal.
If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reason are false.
In the following compound, the number of sp-hybridised carbons are
CH2 = C = CH - CN(CH) - C ≡ CH

CO is practically non-polar since
the sigma electron drift from C to O is almost nullified by the pi-electron drift from O to C
the sigma electron drift from O to C is almost nullified by the pi-electron drift from C to O
the bond moment is low
there is a triple bond between C and O
