Class 12th

Kjeldahl's method is not applicable to compounds containing nitrogen in nitro and azo groups and nitrogen present in the ring.

The name of this SI Unit Henry is derived from the name of the scientist who discovered the concept of inductance and electromagnetic induction, Joseph Henry. He was a scientist from America who supported the principles of Faraday and helped in bringing a revolution in the field of modern physics.

Energy of the complex $\frac{}{}{}_{}$ $=-\frac{2}{5}*4{?}_0+P$

For low spin $d^4$ ${}^{}$ cation

$=1.6{?}_0+P$

KIndly consider the following figure

${}_Z{}^{A}X+{}_1{}^{1}H\to {}_2{}^{4}He+{}_8{}^{16}O$

$Z+1=2+8?Z=9X\to F$

$A+1=4+16\Rightarrow A=19$

$\Rightarrow {}_Z{}^{A}X={}_9{}^{19}F$

${}_7{}^{14}N+{}_Z{}^{A}Y\to {}_1{}^{1}H+{}_6{}^{14}C$

$7+Z=1+6?Z=0$

$14+A=1+14?A=1$

$?{}_Z{}^{A}Y={}_0{}^{1}n$

Kindly consider the following figure

Kindly consider the following figure

The spectrum of H-atom is formulated and drawn by Bohr's model. These spectrums are line spectrum. Lyman series lies in UV region, Balmer Partly lies UV and partly in the visible region and Paschen series lies in the infrared region.

Sodium phenoxide is resonance stabilized hence phenol is most easily soluble in aqueous alkali.
