Prodrug for Phenobarbital.
What is the other name for perspex?
The plastic in perspex (the common US name is plexiglas) is poly(methyl methacrylate).
How many isomers does pentanol have?
12 isomers can be formed. 1-pentene cis-2-pentene and trans-2-pentene 2-methyl-1-butene 3-methyl-1-butene 2-methyl-2-butene 1,1-dimethylcyclopropane (1R, 2R)-1,2-dimethylcyclopropane (1S, 2S)-1,2-dimethylcyclopropane methylcyclobutane cyclopentane and ethylcyclopropane
What are the products from combustion of 2-methyl- and 3-ethyloctane?
Carbon dioxide and water
Is water hydrophobic?
no, that would mean water molecules are not attracted to other water molecules
Which is a better leaving group methyl group or hydride group?
Methyl group is a better leaving group compared to hydride group. This is because methyl group can stabilize the negative charge on the leaving group more effectively than hydride group due to the presence of additional carbon atoms. This makes the departure of a methyl group more favorable in organic reactions.
How does a methyl or hydride shift occur in a chemical reaction?
A methyl or hydride shift in a chemical reaction happens when a carbon atom with three hydrogen atoms attached moves to a different carbon atom, creating a new bond. This shift helps stabilize the molecule by redistributing electron density.
What is the ranking of radicals in order of decreasing stability?
The ranking of radicals in order of decreasing stability is as follows: benzyl allyl tertiary secondary primary methyl.
What is the rank of the following radicals in order of decreasing stability?
The rank of the following radicals in order of decreasing stability is as follows: benzyl radical allyl radical methyl radical.
What is 3-methyl-1-butyne used for?
It is known to be part of the 'Favorskii Reaction' (not the Fav. Rearrangement) Cf. WikiPedia-link in "Related links"
How does the 1,3 methyl shift occur in organic chemistry reactions?
In organic chemistry reactions, a 1,3 methyl shift occurs when a methyl group shifts from one carbon atom to another that is three carbons away. This rearrangement happens due to the movement of electrons, leading to the formation of a more stable molecule.
Why does tetramethyl-lead IV increase the rate of the free radical substitution reaction between methane and chlorine?
Tetramethyl-lead IV acts as a catalyst in the free radical substitution reaction between methane and chlorine by generating methyl radicals through homolytic cleavage. These methyl radicals then react with chlorine to form methyl chloride and regenerate the lead catalyst, thus increasing the rate of the overall reaction.
What base is used in the alkylation of methyl hexanoate with ethyl iodide?
The base commonly used in the alkylation of methyl hexanoate with ethyl iodide is usually a strong base like sodium hydride (NaH) or potassium tert-butoxide (KOtBu). These bases are effective in promoting the deprotonation of the acidic hydrogen on the ester, allowing for the subsequent nucleophilic attack by the ethyl iodide.
How does methyl stearate compare to methyl oleate?
Methyl stearate is a saturated fatty acid methyl ester, while methyl oleate is an unsaturated fatty acid methyl ester. Methyl oleate has a higher degree of unsaturation due to a double bond in its carbon chain, making it more flexible and less rigid than methyl stearate. Additionally, methyl oleate may have different physical properties, such as a lower melting point, compared to methyl stearate.
What is the methyl group associated with?
The methyl group is -CH3.
How do you make dimethyl titanocene?
Dimethyl titanocene can be synthesized by reacting titanocene dichloride with lithium aluminum hydride and methyl iodide in anhydrous conditions. The reaction typically takes place in a nonpolar solvent like diethyl ether and requires careful handling due to the reactivity of the reagents involved. Purification methods such as column chromatography may be employed to isolate the desired product.
3 If Acid-catalyzed dehydration of 22-methyl-1-hexanol gave a number of isomeric alkenes including 2-methyl-2-heptene Write a step-wise mechanism for the formation of 2-methyl-2-heptene?
The acid-catalyzed dehydration of 22-methyl-1-hexanol involves protonation of the hydroxyl group, followed by the loss of water to form a carbocation intermediate. This carbocation undergoes a hydride shift to form a more stable tertiary carbocation. The final step involves deprotonation to form the alkene, resulting in the formation of 2-methyl-2-heptene.
