Title: organic chemistry
Post by: morgan963 on June 09, 2021, 06:04:11 AM
Two students each make a statement about 2-methylbut-1-ene.
Student 1 states that 2-methylbut-1-ene has geometrical isomers.
Student 2 states that 2-methylbut-1-ene reacts with HBr in an addition reaction to give
1-bromo-2-methylbutane as the main product.
Which students are correct?
A both 1 and 2
B 1 only
C 2 only
D neither 1 nor 2

i dont understand how can i know when a compund have geomtrical isomer or not and why HBr cant make addition reaction when there is double bond in this structure

Draw out the structure and see. Do you know what geometrical isomers are?

HBr can make an addition reaction, but is student 2 right about the main product?
