    Maths P3( Vectors)

    Okay let me explain this. When two planes intersect they form a line. To get the equation of this line we apply the elimination method on the equations of the two planes. Now we have to eliminate two of the constants, it can either be x, y or x, z or y, z. It doesn't really matter which two you...

    No price money or ceremony of any sorts for Pakistanis. They have stopped such ceremonies in Pakistan. This shows that CIE is somewhat discriminatory.

    Nucleophilic subsititution or addition?

    Nitration of benzene (it has an electron cloud) is by NO2+ (it is an electrophile), thus it gives an electrophilic reaction. Have a look at the mechanism for clarification: http://pubs.acs.org/doi/abs/10.1021/jo991538u

    Nucleophilic subsititution or addition?

    Nucleophilic reactions occur when a Nucleophile or a Negatively charged species attacks e.g OH-, Cl - etc Electrophilic reactions occur when an Electrophile or a Positively charged species attacks e.g H+, Br+, H3O+
