The ir spectrum of benzilic acid is shown below. for each peak indicated by the blue boxes, select the bond represented by the f
requency.
1 answer:
Below is the structure of Benzilic Acid and IR spectrum. First common thumb rule for elucidating IR spectrum is to find a broad and intense signal between 1690-1800 cm⁻¹, If present! Then its for Carbonyl group. Secondly, watch for broad peak around 3400-3600 cm⁻¹, peak at this frequency is given by the -OH (Hydroxyl) group of Alcohols, andthe broadness is due to Association effect (Hydrogen bonding). Third, aif a wide band between 2500-3300 cm⁻¹ is present it shown -OH of carboxylic acid.
Result:
Carbony Group = 1640 cm⁻¹
Carboxyl -OH Group = 2950 cm⁻¹
Alcohol -OH = 3400 cm⁻¹
Result:
Carbony Group = 1640 cm⁻¹
Carboxyl -OH Group = 2950 cm⁻¹
Alcohol -OH = 3400 cm⁻¹

Answer: The specific heat of the unknown metal is
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed= Joules
m= mass of substance = 86.8 g
c = specific heat capacity = ?
Initial temperature of the water =
Final temperature of the water =
Change in temperature ,
Putting in the values, we get:
The specific heat of the unknown metal is
