Eclipsed chemistry
WebEclipsed (eclipsed conformation ): Two atoms and/or groups whose dihedral angle is 0 o. In other words, their bonds to the axis of rotation are aligned. Also refers to a conformation which contains this arrangement. … WebDefinition of Eclipsed, Eclipsing Two atoms or groups attached to adjacent atoms are said to be eclipsed if the torsion angle between the three bonds is zero (or approximately so). …

WebJan 26, 2024 · Re: Question about NH4Cl. Very true! The conjugate acid of Cl- is HCl, which is a VERY, VERY strong acid. Bases of strong acids are very stable (unreactive), because acid strength = desire to deprotonate into conjugate base. Therefore, Cl- won't impact the pH of the solution. NH4+, though, is the conjugate acid of a weak base, ammonia.

I found one definition online stating that "steric strain is defined as the repulsion felt between atoms at four or more bonds separated from each other forced closer than their van der Waals radius would typically allow".
