arrange the following in decresing order of stability

2>4>3>1 ??

wy is 2>3?

bcoz in 2 the resonating str is i one plane but in 3 ch2 is in other plane

please explain how in 2 and 3 different planes can affect stability.

i think in 3 there will be more delocalisation.....so itshould be 3>2........
ashish can u plz explain

_{2>4>>3>1 as bridge carbanion is least stable 1 are bis leastt stable and as 2&3 are resonance stabilized but in3 the carbanion is out of plane.so 2>3}
