Q. Why the gain of the amplifier decreases if the CE is avoided?
When the ce is connected in the circuit, ac signals get bypassed through it to the ground. In the absence of Ce, ac signals produces voltage drop across Re. In effect, this drop acts as a negative feedback voltage to the base of the transistor. negative feedback causes a decrease in gain.
