Comparison of basic strength of benzylamine and ammonia

According to me, ammonia should be the stronger base for two reasons: $ce{-C_6H_5}$ group shows $-I$ effect, due to which electron density on $ce{N}$ atom of benzylamine decreases steric hindrance in benzylamine is more than that in ammonia But their $mathrm{pK_b}$ values are: benzylamine: $4.70$ and ammonia : $4.75$. High $mathrm{pK_b}$ value of ammonia shows… Read More »

Why electronegativity instead of electropositivity

When I learnt about polarity, I always come to the term electronegativity and always use the electronegativity chart. However, when I studied further, they have the word electroposivity. So, I’ve been thinking why we use electronegavity more often than electropositivity? And why we have a electronegativity chart instead of electropositivity chart?

Finding required drug concentration given Kdiss

The enzyme HIV-1 reverse transcriptae (HIV-RT) plays a significant role for the HIV virus and is an important drug target. Assume a concentration [E] of 2.00 µM (i.e. 2.00 x 10-6 mol/l) for HIV-RT. Two potential drug molecules, D1 and D2, were identified, which form stable complexes with the HIV-RT. The dissociation constant of the… Read More »

Which of the following is polar [duplicate]

This question already has an answer here: Non-zero dipole moment of hydroquinone 2 answers Why does p-dichlorobenzene have zero dipole moment while hydroquinone does not? 1 answer Which of the following is polar ??? I do not know , i think all of these are not polar can you explain to me
