Q. Which of the following reactions would generate an electrophile? (I)(((CH)3​))3​CBr+Anhy.(AlCl)3​ (II) CH3​−CH=CH2​+H⊕ (III) C6​H5​COOH+H3​O⊕ (IV) HNO3​+H2​SO4​

I, II and IV

I, II and III

I, II, III, IV

II, III and IV

Here electrophile generation is possible in reactions I, II and IV as follows (I) (II) CH3​−CH=CH2​+H⊕→CH3​−C⊕H−CH3​ (III) C6​H5​COOH+H3​O⊕→noreaction (IV)(HNO)3​+(H)2​(SO)4​→(NO)2​⊕​+(H)3​O⊕+(H)​SO4−​

Q. Which of the following reactions would generate an electrophile?

$(I) (((CH)_{3}))_{3} CBr + Anhy . (AlCl)_{3}$

$(II)$ $C H_{3} - C H = C H_{2} + H \oplus$

$(III)$ $C_{6} H_{5} COO H + H_{3} O \oplus$

$(I V)$ $H N O_{3} + H_{2} S O_{4}$
