stronger base better nucleophile

protic solvents decrease nucleophilicity by interacting with the electrons in nucleo

dunno y for some reason in protic solvents larger ion will be more nuleophillic

not that u cant.u will get meta nitro anilene and para the isomer.meta product s becoz anilene gets protnated to form anilinium ion which will deactivate the ring and orient the no2 group towards the meta position

in the formula f=ma f is the net force on the body(ie the wall in this case).when u press the wall the wall provides an equal and opposite normal force which is the reason y there is no acceleration(since net force is 0).the extent to which normal force can be provided by any surface depends on the characteristics of that surface.so if u provide a force greater than the maximum normal force which the surface can provide ,the wall will break.


pls use normal english

cheers!!!!

yes,the magnetic moment will be zero.since the magentic moment vectors will be in the opposite directions.each magnet can attract iron pieces.the two magnets will not behave as a single magnet
