What is most reactive propanol, propanal, propanoic acid?

To what?

Think about the polarity of the bonds..... also, what is more reactive, a double or a single bond? What about the relative steric effects of an OH group vs a H group? Or the dislocation of the electrons across the COOH group when in solution?

Well i know that if a carboxylic acid is in solution it exists in the deprotonated form and forms a stable coo- ion, does that mean that propanoic acid is least reactive?

Could u please clarify what u mean by steric effect? I dont think we have covered that at A2.

hi all sorry to drop in on your page. i am also trying to find some help with chem. can any1 help me with this Q

Calcium carbonate decomposes when heated:

CaCO3 (s) > CaO (s) + CO2 (g)

a) What mass of cacium oxide is produced from 150g of CaCO3
b) What volume of carbon dioxide is produced from 150g of CaCO3

IF I NOT WELCOME THANKS ANYWAY

If a reactive part of a molecule has big bulky bits hanging off it, it makes it less able to react. Think of it like trying to get to the bar when there are a team of rugby players in the way.

The carbanion is quite stable, so it means it is less reactive. Alcohol groups are also fairly stable.

what is the Mr of:
- CaCO₃?
- CaO?

What volume does a mole of gas fill?

If you can answer those questions, you can work through the rest.

i realy dont know anything about chem im trying to help my brother his partner died 4 months ago and his dog got ran over yesterday morning he is going though hell and wants to give up on his access course. he only has 5 Q left so i am trying to get them done and handed in for him. he is a top guy please any help would be brill.
