Explain why the C=C stretching mode gives rise to a rather weak IR band in 1-methylcyclohexane, while in its isomer, methylenecyclohexene, the band is of medium to strong intensity.
There are numerous condensations that are closely related to the Perkin reaction. Among these are the aldol /3Badv/, and /A3a/, Knoevenagel, Claisen, and Dickmann condensations. What general class of compounds can be prepared using each of these well-known reactions?
In an unsymmetrical alkene, the boron atom adds predominantly to the least substituted carbon atom. For example, 2-methyl-2-butene gives the products shown below. CH3-C-CH2-CH3 (also has a CH3 single bonded above the C and a BH2 single bonded below the C) 2% CH3-CH-C-CH3 (also has a CH3 single bonded above the C in the CH
A sample of solid monoprotic acid with molar mass equal to 192.3g/mol was titrated with 0.1237M sodium hydroxide solution. Calculate the mass in grams of acid to be used if the volume of NaOH to be used is 25mL. (Stt attachment for full question)
When tert-pentyl bromide is treated with 80% ethanol, the amounts of alkene products indicated below are detected on analysis.
