Reflux is a medical condition in which your oesophagus becomes irritated or inflamed because hydrochloric acid 'backs up' from your stomach which can cause heartburn.

Take a look at http://www.google.co.uk/search?q=ref...-8&hl=en&meta= for more information.

Reflux is to do with boiling organic compunds at a high temperature safely and securely so that it can react and form new compunds.

Reflux is about boiling an organic reaction in a vessel with a condenser on top - so that the vapour can't escape and, instead, condenses and returns to the reaction mixture. It's a way of speeding up the reaction without loosing all the stuff or blowing yourself up!!!

this one is the right answer u can use it when converting a primary alcohol into an aldehyde because if you dont reflux it thtn you gets lots of carboxylic acid instead

Missing a 't' .....

You can't use it to make an aldehyde (alkanal) as it will further oxidise the aldehyde formed which returns to the reaction vessel during the reflux process.

you do use it to make a carboxylic acid from a primary alcohol (and in lots of other organic preparations that involve heating volatile organics that you don't want to escape into the lab)

You can actually use reflux for forming aldehydes if you mix your acidified potassium dichromate and ethanol for example, reflux and distill off the aldehyde as it forms.

if yu distil off it's called distillation not reflux...

reflux is when yu do not allow it to distil off
