2. Prochirality - Wikipedia

   en.wikipedia.org/wiki/Prochirality

   If two identical substituents are attached to an sp 3-hybridized atom, the descriptors pro-R and pro-S are used to distinguish between the two. Promoting the pro-R substituent to higher priority than the other identical substituent results in an R chirality center at the original sp 3-hybridized atom, and analogously for the pro-S substituent.

3. Bent's rule - Wikipedia

   en.wikipedia.org/wiki/Bent's_rule

   In traditional hybridisation theory, the hybrid orbitals are all equivalent. [12] [27] Namely the atomic s and p orbital(s) are combined to give four sp i 3 = 1 ⁄ √ 4 (s + √ 3 p i) orbitals, three sp i 2 = 1 ⁄ √ 3 (s + √ 2 p i) orbitals, or two sp i = 1 ⁄ √ 2 (s + p i) orbitals. These combinations are chosen to satisfy two ...

4. Bredt's rule - Wikipedia

   en.wikipedia.org/wiki/Bredt's_rule

   Bredt's rule also applies to carbocations and, to a lesser degree, free radicals, because these intermediates also prefer a planar geometry with 120° angles and sp 2 hybridization. It generally does not apply to hypervalent heteroatoms, although they are commonly written with a formal double bond. [6]

   Life insurance is designed to provide a death benefit for your loved ones if you pass away. Long-term care insurance, meanwhile, can help pay for long-term care expenses while you're still living.

6. Aldehyde - Wikipedia

   en.wikipedia.org/wiki/Aldehyde

   Aldehyde molecules have a central carbon atom that is connected by a double bond to oxygen, a single bond to hydrogen and another single bond to a third substituent, which is carbon or, in the case of formaldehyde, hydrogen. The central carbon is often described as being sp 2-hybridized. The aldehyde group is somewhat polar.

7. Carbon–carbon bond - Wikipedia

   en.wikipedia.org/wiki/Carbon–carbon_bond

   The carbon–carbon single bond is a sigma bond and is formed between one hybridized orbital from each of the carbon atoms. In ethane, the orbitals are sp 3-hybridized orbitals, but single bonds formed between carbon atoms with other hybridizations do occur (e.g. sp 2 to sp 2). In fact, the carbon atoms in the single bond need not be of the ...
