Eclipsed organic chemistry
Conformations can be described by dihedral angles, which are used to determine the placements of atoms and their distance from one another and can be visualized by Newman projections. A dihedral angle can indicate staggered and eclipsed orientation, but is specifically used to determine the angle between two specific atoms on opposing carbons. Different conformations have unequ… WebThe Newman projections show that propane has a set of eclipsed and staggered conformations similar to ethane, but with a torsional strain of 3.3 kcal/mol. Each eclipsed conformation now consists of two eclipsed C-H …

WebStaggered conformation. In organic chemistry, a staggered conformation is a chemical conformation of an ethane -like moiety abcX–Ydef in which the substituents a, b, and c are at the maximum distance from d, e, and f; this requires the torsion angles to be 60°. [1] It is the opposite of an eclipsed conformation, in which those substituents ... WebDec 7, 2016 · The two terms, Staggered and eclipsed conformation(two main branches of the Newmann projections) are used in Organic Chemistry to explain the arrangement of atoms in some organic …

Comment on … 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.
