p & l statement

p - p p back bonding The tendency for back donation is maximum in the case of fluorine due to its small size and more inter-electronic repulsions. Therefore, it is the least acidic. The tendency of back bonding falls as we move from BF 3 to BCl 3 and BCl 3 to ..

Carbon forms p p -p p multiple bonds to itself, and to other elements, particularly nitrogen and oxygen. This results in the formation of a large number of compounds containing C = C, C C, C = O, C = N, C N and C = S bonds. For example ..

For p-orbitals (l=1), there are three possible orientations corresponding to m = -1, 0, +1 values. This means that there are three p - orbitals in each p-subshell. These are designated as p x , p y and p z ; For e.g., 2p x..

pH is the negative logarithm of H 3 O + ion concentration in moles/litre pH of water = 7 at 298 K pH of acids = less than 7 pH of bases = greater tha..

If a,b,c,d are in A.P., then (ii) ka, kc, kb, kd are also in A...

c ) The pressure required to liquefy the gas at its critical temperature is called critical pressure. For example, the value of P c for CO 2 = 55328 mm of ..

Neutral Salts - A neutral salt arises due to the neutralization reaction. Here, salts of strong acid and strong base combine to form such salts that show a neutral pH of ..

Some Properties of A.P. - If a,b,c,d are in A.P., then (ii) ka, kc, kb, kd are also in A.P. A remark on finding a few members of an A.P. whose sum is given along with other conditions: i) If the sum of three numbers in A.P. is given, take the number..

If a,b,c,d are in A.P., then (ii) ka, kc, kb, kd are also in A.P. A remark on finding a few members of an A.P. whose sum is given along with other conditions: i) If the sum of three numbers in A.P. is given, take the numbers as a-d, a, a+..
