Which compound would give 5 - keto - 2- methyl hexanal upon ozonolysis ?
A signal of 5 kHz frequency is amplitude modulated on a carrier wave of frequency 2 MHz. The frequencies of the resultant signal is/are :
In a hydrogen like atom electron makes transition from an energy level with quantum number n to another with quantum number (n - 1). If n>>1, the frequency of radiation emitted is proportional to
Compound (A), C8H9Br, gives a white precipitate when warmed with alcoholic AgNO3. Oxidation of (A) gives a acid (B), C8H6O4. (B) easily forms anhydride on heating. Identify the compound (A).
Consider a spherical shell of radius R at temperature T. The black body radiation inside it can be considered as an ideal gas of photons with internal energy per unit volume u=VU∝T4 and pressure p=31(VU). If the shell now undergoes an adiabatic expansion the relation between T and R is :
