So in this question there are three compounds a, b and c and we have to rank them by the lambda max.
00:07
So here we know that this thing, see here, this here this is undergoing conjunction, only two.
00:16
But here this is undergoing conduction in three steps and here there is no conjugation.
00:22
So where there is conjugation, the system becomes more stable.
00:26
So when the system becomes more stable, then the energy gap that is delta e, so you can write here, more stable system is, more stable system, okay, the energy gap, that is delta i between the homo and lumo decreases and we know that delta e equal to hc by lambda.
00:47
So when this delta e decreases, okay, delta is inverse to also lambda, okay, so when this decreases, lambda will increase.
00:56
So we can say that when there is conjugation, so when there is conjugation it leads to increased stability, there is decreased delta e and it increases the lambda max value...
