1>3>4>2 Explanation- Base strength of a species is its ability to accept H+ from another species. The greater the ability of a species to accept a H+ from another species, the greater its base strength. For acids: the stronger the acid, the smaller the pKa For bases: the stronger the base, the larger the pKa For example: In HCOOH the conjugate base is HCOO^- which is more stable as it accept H+ Read more on Sarthaks.com - https://www.sarthaks.com/993/arrange-in-order-of-acidic-strength-with-explanation check the below order
got it??
but ans is 4 1 3 2
