An ethyl cation is more stable because the carbon adjacent to the positively charged carbon has three sigma bond orbitals available for overlap with the vacant p orbital, whereas methyl cation does not have any sigma bond orbitals available for overlap with the vacant p orbital.
the case of cyclopropylalkyl cation and substituted cyclopropyl cations is interesting. Cyclopropylmethyl cation has been found to be more stable than benzyl cation and the stability increases with each addition of cyclopropyl groups. This increased stability has been explained between the bent orbitals of cyclopropyl rings and the vacant p orbital of the cation carbon. The vacant p orbital lies parallel to C2-C3 bond of the cyclopropane ring and not perpendicular to it. Thus the geometry becomes similar to that of a cyclopropane ring conjugated with an olefinic bond.
It depends on the specific application. Ethyl acetate is generally considered safer and less toxic than methyl acetate, but methyl acetate can be more environmentally friendly because it has a lower VOC content. Both have different strengths and weaknesses depending on the context in which they are being used.
Aromatic compounds are resonance stabilized. Hence if a compound is aromatic it is more stable. The main thing to note here is that AROMATICITY GIVES STABILITY TO A COMPOUND. Therefore cyclopropene is an aromatic compound and hence is more stable than propene.
Cellulose has 3 hydroxyl (OH) groups on each glucose unit. Methyl cellulose replaces these hydroxyl groups with methoxy (OCH3) groups. Therefore it follows that these groups are now replaced with ethoxy groups or (OCH2CH3) groups.
No, toluene is less polar than ethylbenzene. Toluene has a methyl group attached to the benzene ring, which decreases its overall polarity compared to ethylbenzene, which has an ethyl group attached.
Ethyl alcohol shows maximum hydrogen bonding with water because it has an additional -CH2 group compared to methyl alcohol, providing more sites for hydrogen bonding with water molecules.

Methanol, also known as methyl alcohol, is madeof molecules containing one methyl group, with a chemical structure of CH3-OH. Methanol is highly toxic if inhaled, drunk, or absorbed through the skin and can cause blindness. Ethyl alcohol is the same as ethanol or grain alcohol. I has two methyl groups and looks like CH3-CH3-OH. This is the type of alcohol found in the alcoholic beverages people consume. Both compounds are organic and are good solvents and fixatives.
Aromatic compounds are resonance stabilized. Hence if a compound is aromatic it is more stable. The main thing to note here is that AROMATICITY GIVES STABILITY TO A COMPOUND. Therefore cyclopropene is an aromatic compound and hence is more stable than propene.
Do a E1 elimination reaction (using a weak base, such as a hot alcohol). The initial primary cation formed is unstable, and a methyl shift will result in a more stable secondary cation. Elimination of the tertiary proton will give you 2-methyl-2-butene as the major product (zaitsev's rule - it is the more substituted product). Elimination of the primary proton will also get you some amount of 3-methyl-1-butene (the hoffman product).
Cellulose has 3 hydroxyl (OH) groups on each glucose unit. Methyl cellulose replaces these hydroxyl groups with methoxy (OCH3) groups. Therefore it follows that these groups are now replaced with ethoxy groups or (OCH2CH3) groups.
There are more than 20 stuctural isomers of hexene C6H12, including various branched (cis and trans) and cyclic compounds (eg. cyclohexane, methyl-cylopentane, 1,1-dimethyl-cyclobutane, 1,2-dimethyl-cyclobutane, 1,3-dimethyl-cyclobutane, and some other, maybe not stable, propyl/methyl-ethyl/trimethyl-cyclopropanes) Some of them also count for optical isomerism (eg. 3*-methyl-1-pentene)
Methyl Alcohol is not a product of fermentation so no steps are required to avoid it. You are morelikey to get annoying levels of Ethyl Acetate which is solvent smelling and tasting. Methyl Alcohol can be found in trace amounts in wine and fruit brandies but this is due to the breakdown of pectin the the cell walls of the fruit and not fermentation. Its worth noting that the treatment for Methyl Alcohol poisoning is ingestion of Ethyl Alcohol. Both are prcessed by the same enzyme which much prefers to breakdown Ethyl Alcohol. Basically they keep you drunk until all the Methyl Alcohol has been sweated/breathed/urinated out of your system. Methyl Alcohol isn't actually poisonous, BUT its metbolised by your body into chemicals that are. Any product of fermentation containing Methyl Alcohol will contain more than enough Ethyl Alcohol to protect you from it. Anyone concerned about Methyl Alcohol ingestion should read up on Aspartame. The Diet Coke you drink may exposure you to more methanol than you realise.
Methyl orange red at (and below) pH 3.1, turning yellow at pH 4.4 (and up)
No, toluene is less polar than ethylbenzene. Toluene has a methyl group attached to the benzene ring, which decreases its overall polarity compared to ethylbenzene, which has an ethyl group attached.
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.
