َQ9

Answer 1

hmmm
u do know PV= nRT right?

Answer 2

okay i can't wait till u reply coz im gonna be leaving now
anyways
since they talk about Pressure lets make it as subject
\[P = nRT \div V\]
next they are saying we can ignore moles so lets get rid of moles
\[P = RT \div V\]
owwkay
now
ur starting compound is C12H22O11
and it gets hydrolyzed thus broken down
suppose C12H22O11 has some volume
if this compound was to break down, what would happen to the volume?
it would decrease right? i mean it broke down and now its less then before since its broken to 2 different compounds right?
so if ur formula is originally
\[P = RT \div V\]
but now you volume decreased
whats gonna happen to ur pressure? it would increase wouldn't it?
because now RT will divide by smaller number right?
that's why Pressure Increases

now about glucose and fructose
if u count number of carbons in glucose and fructose, the no. is same right? but they are still different compounds right?
they are NOT optical isomers because
optical isomers have chiral center as u should be knowing and isomer of optical isomer is its own mirror image
its not happening in case of glucose and fructose
glucose and fructose are Functional group isomers or Structural isomers
thus the answer should be now clear to u)
if still not clear feel free to ask :D
