    +M effect of OH greater than OCH3 Explanation:- The -R group in -OR causes steric repultions with lone pairs, increasing bond angles. Due to which %s character is increased; making -O- atom of -OR more electro-negative and thus affecting donor tendency.

    lone pair ke sath repulsions hone se bond angle badhta hai...and bond angle directly proportional to percentage s character which is directly proportional to electronegativity...so donor tendency kam ho jayenge

    +R effect of OCH3 is more than that of OH group. +R effect: The groups show positive mesomeric effect when they release electrons to the rest of the molecule by delocalization. These groups are denoted by +M or +R. Due to this effect, the electron density on rest of the molecular entity is increased.

    kha problem aa rhi he

    eduncle-logo-app

    jb O ka lone pair resonance me jayega to O pr + charge ayega or CH3 ka +I effect hota he to ye O ke + charge ko jada stabilized krega so more +R than OH

    +r Ka yhan mtb kya hai

    eduncle-logo-app

    apne hi to pucha +R kiska jada he

    eduncle-logo-app

    yes, pr apne jo pucha usi ka to reply kiya he. apka Ques tha ki kiska +R jada hoga och3 or OH me se to uska reson diya he
