A sample of oxygen gas is collected by downward displacement of water from an inverted bottle. The water level inside the bottle is equal with that in the trough. The pressure is found to be 757 mmHg and temperature is 290 Kelvin. What is the partial pressure of oxygen.
Is the move from pi bonds to sigma bonds always favorable?
My professor claims so, except in the case of conjugated pi bonds. I can see how pi bonds going to sigma bonds might be favorable; I know that double bonds are actually not twice as strong as single bonds because of poorer overlap ... b...
In case (b) the carbanion is always destabilized by a $\ce{+I}$ effect by an alkyl group directly attached to the negative charge bearing carbon.
This is not the case with (a) as no alkyl groups are directly attached to it.
Well I know for a fact that cis alkenes are less stable than trans alkenes due to steric repulsions.
But what bugs me is the fact that why systems such as 2-Methylprop-1-ene (where I believe steric repulsions are greater than that in cis-But-2-ene) are stabler than its cis and trans counterparts...
