I COULD UNDERSTAND UR DOUBT
THAT Y S-2 IS WRONG EVEN THOUGH IT LOOKS PERFECTLY F9
THE CONCEPT HERE IS :
ABSOLUTE SN1 AND ABSOLUTE SN2 NEVER OCCURS
THERE IS ALWAYS A COMPETITION BETWEEN BOTH OF THEM
IN CASE OF 3° SN1 DOMINATES AND IN CASE OF 1°,2°AND THE METHYL DOMINATES
BUT WHEN 2°RX REACTS IT DEPENDS UPON THE CONDITIONS WAT WILL TAKE PLACE
BUT TO BE TRUE I ALSO GOT IT WRONG I THOUGHT IT WAS A
BUT !!!!!!!!!
1yaar in formate resonating structures are equivalent i.e. symmetric...whereas in benzoate all the structures are different and also in formate resonating structures the negative charge is on oxygen whereas in benzoate resonating structures the negative charge is on less electronegative carbon atom in some resonating structures....

DON'T GIVE THE ANSWERS B4 U GET THE SOLUTION
THIS WILL DAMPEN UR SPIRITS AND MAKE UR CONCEPTS POOR
1HEY FRIENDS PLSSSSSSSSSSSSSSSSSS GIVE EXPLANATIONS [2]
AND MECHANISM.. of the formation
1For 3rd, i think it's d bcoz benzoate ion is more stable than formate due to resonance. But i dunno how c[7]
