Correct order of increasing basic strength is R-COO(-) < CH ≡ C(-) < NH (-)2 < R(-)

Q. The correct order of increasing basicity of the given conjugate bases $(R = C H_{3})$ is

$RCO \overset{ˉ}{O} < H C = \overset{ˉ}{C} < \overset{ˉ}{R} < \overset{ˉ}{N} H_{2}$

$\overset{ˉ}{R} < H C \equiv \overset{ˉ}{C} < RCO \overset{ˉ}{O} < \overset{ˉ}{N} H_{2}$

$RCO \overset{ˉ}{O} < \overset{ˉ}{N} H_{2} < H C \equiv \overset{ˉ}{C} < \overset{ˉ}{R}$

$RCO \overset{ˉ}{O} < H C \equiv \overset{ˉ}{C} < \overset{ˉ}{N} H_{2} < \overset{ˉ}{R}$

Correct order of increasing basic strength is
$R - CO O^{(-)} < C H \equiv C^{(-)} < N H_{2}^{(-)} < R^{(-)}$
