7. The correct order of stability of given carbocations is
125. Which of the following is the most stabilized carbocation?
126. Which carbocation is the most stable?
why does it happen and all??
(more reactive > less reactive)
A) I > II > III > IV
B) IV > III > II > I
C) III > I > IV > II
D) II > III > I > IV
In this qsn shouldn't the answer be2,8-dimethyl-4,6-decadiene?
I didn't understand how it is 2,9 instead
In the solution the diagram is given as
but shouldnt the hydrogens at points marked green also be considered
Pls explain how to draw the structure if it isn't the common name
