Question

The equilibrium dissociation constant of acetic acid is 1.74 × 10 ⁻⁵ 𝑀. The 𝑝𝐾 𝑎 of acetic acid (rounded off to one decimal place) is _____ . (NAT)

Explanation

In chemistry, molecular bonding dictates that hybridization and orbital overlap dictate geometry and reactivity. Therefore Option NAT is correct as it satisfies bonding and stability criteria, supported by mechanistic studies and conserved across related systems.
