Hi,I m in blind passage.In my exercise book is one question,which asks:
Compound CH3-CH2-O-CHOH-CH2CH3 can be made from: a)ethanal
b)propanal
c)acetaldehyde
d)methanol
e)ethanol
f)propanol
g)methanal
h)propionic acid
Corrects answers are b) and e).And I m asking,why just these ones?Why cannot be made from for example propanol?
Thanks
