There are four isomers of alkenes, which have the chemical formula C4H8, but different structures. The IUPAC (and common) names, respectively, are: but-1-ene (α-butylene), cis-but-2-ene (cis-β -butylene), trans-but-2-ene (trans-β -butylene) and 2-methylpropene (isobutylene). Beca...
Geometrical isomers differ in: View Solution Draw the geometrical isomers of but-2-ene. View Solution Give reasons for the following: Isomers belonging to the same homologous series may differ in physical properties but not in chemical properties. ...
is a tasteless and odorless white crystalline powder practically insoluble in hexane or water, slightly soluble in ether, and very soluble in dichloromethane, methanol and acetone. Chemically, it is 11β,17,21-trihydroxypregn-4-ene-3,20-dione 17-butyrate 21-propionate. The structural formula is...

Mice were allowed to recover from the surgery for 2–4 weeks before the first imaging session. Intrinsic signal imaging Whisker-evoked sensory activity maps were generated using ISI69. Animals that were sedated with chlorprothixene (~3 mg/kg, i.p.) and lightly anesthetized with ~0.5–0.7...
Molecules 2012, 17 14539 This is also in agreement with the course of the base catalyzed reaction of 1a with E-1,4-dibromo- but-2-ene at elevated temperature. The first step obviously forms the (mono)anion E-12 through O-allylation of 1a (Scheme 5). Formally this intermediate can ...

(A) is false. They are not position isomers , since the position of the double bond has not changed, they are chain isomers. (R ) is true.
