Why do alkyl halides undergo the nucleophlic subtitution reaction?
haloarenes are less reactive than haloalkanes because: 1. resonance effect more the resonatinsg structures,more the stability 2.difference in hybridisation of the C-X bond i.e.,in haloalkanes,the hybridisation is sp3 whereas in haloarenes it is sp2 hybridised.As sp2 is more electronegative therefore bond length is shorter and hence stronger. these are the major reasons.
Do alkanes and haloalkanes conduct electricity?
Both alkanes and haloalkanes are not electrically conductive.
What is formed when metals act on haloalkanes?
When a metal reacts with a haloalkane it forms an organometallic reagent such as Alkyllithium (RLi) or the Grignard Reagent (RMgX) where R is an alkane and X is a halogen.
What kind of reaction -SN1 or SN2 or E1 or E2- is expected for secondary haloalkanes with sterically hindered strong bases?
the mostly undergo SN1 or E1.. but ratio of E1 is higher...
Why do secondary haloalkanes (like 3-chloropentane) give poor yields with the Williamson ether synthesis?
Because they have been reacted with primary sulfonate under typical SN2 condition.
What has the author Aldo Tomasi written?
Aldo Tomasi has written: 'The metabolism of some haloalkanes to free radical intermediates studied by electron spin resonance spectroscopy andthe spin trapping technique'
Why the brown color of bromine disappear when mixed with cyclohexene?
Halogens react with alkenes to form haloalkanes. Addition of the bromine in this case occurs across the double bond in cyclohexene. The resultant products are colourless hence the brown colour disappears.
Why the electrophilic substitution reaction of haloarenes is oRtho and pera directing?
Because the +R effect of the haloarene, tends to oppose the -I effect, and hence the deactivation is lesser at the ortho and para positions, compared to any other position (like the meta position). So they tend to be o-p directing.
What is an alkylating agent?
An alkylating agent is a compound that's capable to replace a hydrogen for an alkyl group to a specific place on a molecule. Alkylating agents attacks mostly on a nitrogen, oxygen or sulfur. Common alkylating agents are: Methyl iodide(or other haloalkanes), dimethylsulfate and some carboxylic acid alkyl esters.

Why do haloalkanes have a higher boiling point than alkanes?
cycloalkanes have a higher boiling point than alkanes because there are more points of contact between the carbon-carbon chain, and thus more intermolecular Van Der Waal (or London) forces. Similarly, the boiling point of alkanes increases as the length of the carbon chain increases. This is because more intermolecular forces are present, hence more energy in heat form is required to break the bonds. Branching in the alkanes reduces the boiling point as it reduces the points of contact.
Four classes of organic molecules are?
There are far more than four classes of organic molecules; there are easily hundreds, possibly a thousand. Some of them include alkanes, alkenes, alkynes, alcohols, aldehydes, ketones, carboxylic acids, benzenes, phenols, amines, amides, acid/acyl chlorides, amino acids, sugars, proteins, mustards, haloalkanes, haloalkenes, opiates, opioids and more.
