(a) NaOH (b) KOH (c) NH4OH (d) C2H5 OH​

Answer 1

Answer:

d is correct ...... ...

Answer 2

$C_2H_5OH$ is not a base.

• NaOH and KOH are strong bases called sodium hydroxide and potassium hydroxide and can react with acids to form a salt as follows-
• $NaOH/KOH+HCl\rightarrow NaCl/KOH+H_2O$
• $NH_4OH$ is a weak base called ammonium hydroxide.
• $C_2H_5OH$ is not an acid, not a base. It is an alcohol called ethyl alcohol which is widely used for any purpose.
• Hence the correct option is d.
