A ,The question is based on the reactivity series! The higher metal produces more yield than the lower metal

yup that's the answer... but i got confused by the mixture. wat about that?? and how does the VOLUME of hydrogen produced differ?? reaction speed differ karey to smjh mein ata hai but volume to same nhi hona chahiye??

Could anyone possibly explain how the structure of Ester is constructed?
I got it wrong in ATP!
Dont want that to happen in P1 or P2

when the acid and alcohol are added to each other, OH(hydorxide) and H(hydrogen) are taken to produce water, and the empty space will be the area of linkage between the leftovers of thealcohol and acid :D
the name is made by using the name of the alcohol as first name and acid as 2nd ( methanol alcohol + ethanoic acid --> methyl ethanoate )

Reply appreciated! But the WAY HOW THE STRUCTURE is constructed is needed!

when you name it alcohol comes first

Dont know why but XPF becomes more fun and addictive when the subject being discussed totally depends on General concepts(Physics) then MORE of a crammed subject(Chemistry).

I know most wont agree, but this is how I feel!
