Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats..
Analyse the situation by all the data you already have first before making a prediction
So first you see
A primary halide
A very high possibility that it will go an SN2 Reaction
Okay
We read further
Ethanol
A weak nucleophile
Then we see EtONa
Which is a strong enough base and good nucleophile
Now we also see one more thing
EtSNa
Now S based nucleophiles would be relatively less reactive or nucleophilic
Why? Stability of negative on sulphur because of that extra shell that gets added
So the sulphur one is out of question
(for being the major choice)
Now we have 2 options
Either a substitution or an elimination
But as it’s primary halide, less steric hindrance in the SN2 transition state
This leads to the substitution product being major
Aaah I missed one thing
Substitution by what? OH or OEt?
Now you gotta see which of these is more nucleophilic
