Aldehyde Phenol Ether

NEET PYQS

Phenol Prepared From Diazonium salts

✓Diazonium salt is formed by treating
an aromatic primary Amine with
Nitrous Acid (NaNO2+HCl) at 273-278k

✓After Diazonium salts are formed ,
Now Diazonium salts are hydrolysed to
Phenols By

Alcohol Phenol Ether

NEET PYQS

Preparation of Phenol From Cumene

✓Phenol is manufactured from the
hydrocarbon (Cumene)

✓Cumene is Oxidised in the presence of
air to Cumene Hydroperoxide

✓Cumene Hydroperoxide converted to
phenol and acetone BY treating it with
dilute acid

✓Acetone is By-product

⭕️Endoplasmic Reticulum⭕️

(1) Definition: It is well developed electron microscopic network of interconnected cisternae, tubules and vesicles present throughout the cytoplasm, especially in the endoplasm.

(2) Discovery: Garnier (1897) was first to observe the ergastoplasm in a cell. The ER was first noted by Porter, Claude, and Fullman in 1945 as a network. It was named by Porter in 1953.

Golgi Complex
(1) Definition: Golgi complex is made up of various membranous system e.g. cisternae, vesicles and vacuoles.

(2) These are also called golgi bodies, golgisomes, lipochondrion, dictyosomes, Dalton complex, idiosomes or Baker’s body.

(3) These are also called “traffic police” of the cell.

(4) Discovery: First observed by George (1867) but it’s morphological details were given by Camillo Golgi (1898), in nerve cells of barn fowl and cat .
