Chloroacetic acid is a stronger acid than acetic acid. This can be explained using

Match List-$I$ with List-$II$:
| List-$I$ (Mechanism steps) | List-$II$ (Effect) |
| :--- | :--- |
| $(A)$ Aniline resonance structure | $(I)$ $-E$ effect |
| $(B)$ Electrophilic addition of $H^+$ to alkene | $(II)$ $-R$ effect |
| $(C)$ Nucleophilic addition of $CN^-$ to alkene | $(III)$ $+E$ effect |
| $(D)$ Nitrobenzene resonance structure | $(IV)$ $+R$ effect |
Choose the correct answer from the options given below:

The arrangement of $CH_3-CH_2-CH_2-$,$(CH_3)_2CH-$,and $(CH_3)_3C-$ groups in increasing order of their inductive effect ($+I$ effect) is:

In which of the following molecules do all the effects,namely inductive,mesomeric,and hyperconjugation,operate?

How is the inductive effect different from the resonance and electromeric effects?

Which of the following is the most unstable carbocation?
