    sir weak nucleophile give substitution product ? and sir in h2so4 ,oxygen has lone pair but due to resonance it doesn't undergoe substitution reaction right?

    here weak nucleophile can give substitution but product will be in very less amount here case is different. here nucleophile is very weak and nucleophilic substitution is in compitition with elimination reaction so elimination will prefer

    yes, In H2SO4, lonr pair is in conjunction so it is weak nucleophile and can't give nucleophilic substitution
