Q3: Which substances have a higher boiling point than its functional group isomer?
1.
2.
3. CH3CH2CH2CHO,how do students know if option 3 is correct/wrong?
As for the BeF2 question, how does the NaF bond with BeF2?
Either Cambridge won't ask such an unfair question, and/or they will set the options such that the candidate can reasonably eliminate an unknown 1/2/3 option based on the options A/B/C/D available.
Each of the two F- (ion) Lewis bases donates one dative bond to the B (atom) Lewis acid.
Thanks!! :)
