Arceus11: Is it clearer now?
Anonymous07: Bro, Read the question again.
Anonymous07: I have doubt btw. 2nd and 4th option.
Arceus11: heck yeah
Arceus11: i think it is 3rd one
Anonymous07: I don't think so because it will show resonance.
Anonymous07: During resonance, left carbon will get positive charge and thus will give sn2 fast.
Arceus11: When a positive charge is formed it is SN1 and not SN2
Anonymous07: When an atom is removed then that compound gets positive charge.
Arceus11: You are being mistaken

Answer: I guess, The answer is option 2, because all the options are primary and Sn² reactivity series : Ch₃°>1°>2°>3> but in the 2nd option Ch₃ which is electron pushing group, is attached to Ch at second position from the left side which can affect the incoming nucleufile to not attach easily.

Anonymous07: I shared the mechanism of Sn2 in brainly
Anonymous07: earlier
Arceus11: Hmm
Arceus11: No carb-o-cation is formed in sn2
Arceus11: Hence your logic is invalid
