Benzene's delocalised π system of electrons makes it not quite electron rich enough for the reaction to take place. The lone pair from the -OH group in phenol adds enough electron density into the ring so...

So what we need to do is work out what x is when y is equal to 11.Firstly, we would rearrange the equation so that x is the subject and to do this we subtract 5 from both sides.Thisgives us y-5 =2x. Divid...

The first reason as to why the statement is not valid is because of the use of protest and student groups. This makes the statement less valid because, despite facing opposition, protest groups were influ...

3x+1/(x+1)(2x+1)=A/(x+1) + B/(2x+1)Multiply equation by (x+1) and (2x+1) to get:3x+1= A(2x+1) + B(x+1)Let x=-1 (x+1=0 so x=-1) sub into new equation. -2= A(-1) + B (x+1)-2=-AA=2Let x=-1/2 and sub into sam...

A whip is the term for an individual who is a member of a political party in parliament (an MP). The leadership of the party relies on the 'whip' to try to ensure that all the members of the party are vot...
