Vedclass · Answer

(C) Stability of $CH_3-C^+=O$ vs $CH_3-C\equiv O^+$: The acylium ion $CH_3-C\equiv O^+$ is more stable because every atom has a complete octet,whereas $CH_3-C^+=O$ has an incomplete octet on carbon. Thus,the order is incorrect.$(B)$ Acidic strength: $2$-fluorobenzoic acid is a stronger acid than $2$-chlorobenzoic acid due to the stronger $-I$ effect of $F$ compared to $Cl$ and the ortho effect. The given order is incorrect.$(C)$ Bond length: In $N,N$-dimethyl-$2,6$-dimethylaniline,the $N-C$ bond length $(l_1)$ is longer than in $N,N$-dimethyl-$3,5$-dimethylaniline $(l_2)$ due to steric inhibition of resonance. The order is correct.$(D)$ Stability of phenoxide ions: The stability order of nitrophenoxide ions is $p$-nitrophenoxide $>$ $o$-nitrophenoxide $>$ $m$-nitrophenoxide. The given order is incorrect.Therefore,only $C$ is correct. However,based on the provided options,if we re-evaluate the question,$C$ is the only correct statement.

Column-$I$	Column-$II$
$(A)$ Carbocation	$(1)$ Cyclohexane and $1$-hexene
$(B)$ Nucleophile	$(2)$ Conjugation of electrons of $C-H$ $\sigma$-bond with empty $p$-orbital present at adjacent positively charged carbon
$(C)$ Hyperconjugation	$(3)$ $sp^{2}$ hybridised carbon with empty $p$-orbital
$(D)$ Isomers	$(4)$ Ethyne
$(E)$ $sp$ hybridisation	$(5)$ Species that can receive a pair of electrons
$(F)$ Electrophile	$(6)$ Species that can supply a pair of electrons
