TrueTears question thread

[jules]

just a quick question.
Which of the these two are in the same homologous series as 1-chloropropane?

1-Chlorobutane

OR

1,1 Di-chloropropane.

Thank you !

Also . Is that hydrolysis or substitution or both?

[hyperblade01]

 .

Where did the Na come from O.o, did you mean HCl?

Personally, I'd say it was both as you are substituting a functional group and water is a reactant.

LOL sorry, yeah it's HCl, =.=

Alright so both would be marked correct on the exam?

[hyperblade01]

You never know what VCAA will do -.-"

I guess it depends on what's the emphasis...put both down just incase?

Sorry if it doesn't clear up anything but this kinda stuff is hard (in a different sense)

Alright cool thanks for the help. Let's see what Mao/chem-nerd has to say on this

I thought hydration was when you add water over double bonds or summat

[Mao]

oops, my bad. The reaction is NOT hydration (addition of water over a double/triple bond), and it is NOT hydrolysis (addition of water to break a molecule)

It is only substitution

[chem-nerd]

Thank you !

Also . Is that hydrolysis or substitution or both?

hmm, don't forget that this reaction would require a catalyst, it would be more usual to react chloroethane with NaOH/KOH

it would be safer to classify it as a substitution reaction (although it is also a hydrolysis reaction)

Ah thanks, what catalyst would be suitable for this reaction?

[monokekie]

if i am not wrong, boiling it would do

Usually isn't the catalyst just H+ so it is in an acidic environment?

[chem-nerd]

for ethene + water -> ethanol you need an acidic environment and high temp (usually H₃PO₄ and 300C)

for chloroethane + water -> ethanol usually is done with either NaOH or KOH

[Mao]

Other reactions requiring acidic environment: condensation/esterification
