Is salt soluble in cyclohexane?
Cyclohexane is a typical nonpolar solvent. The substances that you will try to dissolve will be of three bonding types: ionic, such as NaCl; nonpolar covalent, such as paraffin wax; and polar covalent, such as ethanol.
Is sugar soluble in cyclohexane?

What is cyclohexane soluble in?
Cyclohexane is a colourless, mobile liquid with a mild, sweet odour. It is slightly soluble in water and soluble in alcohol, acetone, benzene, ethanol, ethyl ether, olive oil, and carbon tetrachloride. Melting Point: 6.47°C.
Why is cyclohexane soluble in water?
Cyclohexene is a non polar molecule and water is polar molecule as it has sufficient electronegativity difference between the constituent atoms. So cyclohexene won’t be aoluble in water. Instead it will be soluble in non polar solvents like benzene.
Is chlorobenzene soluble in water?
Practically insoluble in water and somewhat denser than water (9.2 lb / gal). Vapors heavier than air. Used to make pesticides, dyes, and other chemicals. Chlorobenzene is the simplest member of the class of monochlorobenzenes, that is benzene in which a single hydrogen has been substituted by a chlorine.
What is the formula of chlorobenzene?
C6H5Cl
What is correct for chlorobenzene?
So, electrophile will attack at Ortho/Para position in chlorobenzene. So, Cl is ortho/para directing and shows + M effect due to non-bonding electrons and it is deactivating due to high electronegativity. Therefore option (D) Cl is Meta directing, is correct.
Why is chlorobenzene Ortho para directing?
Chlorine atoms shows an electron releasing nature due to resonance effect. The lone pair present on the chlorine atom delocalize itself with pi-electrons of the ring. The electron release into the ring stabilizes the positive charge at ortho and para positions due to attack of an electrophile .
Is a methyl group ortho para directing?
Thus, the methyl group is an ortho, para directing group. Thus, the nitro group is a meta directing group. Ortho, para directing groups are electron-donating groups; meta directing groups are electron-withdrawing groups.
Why halogens are ortho para directing?
Halogens are very electronegative. This means that inductively they are electron withdrawing. However, because of their ability to donate a lone pair of electrons in resonance forms, they are activators and ortho/para directing. Electron withdrawing groups are meta directors and they are deactivators.
Why does chlorobenzene undergo electrophilic substitution at ortho and para position?
As a result of which the electron density of the aromatic ring decreases and deactivates the ring. Chlorobenzene is less reactive than benzene towards electrophilic substitution reaction. Hence chlorobenzene is ortho para deactivator and is less reactive than benzene.
Which is least reactive in electrophilic substitution?
Benzenesulphonic acid
Why do electrophilic substitution is ortho para directing in Haloarenes?
In the resonance structures of chlorobenzene the ortho and para positions get negatively charged, i.e. the electron density is relatively more at ortho and para positions. The incoming electrophile is more likely to attack these positions.
Which is more reactive fluorobenzene or chlorobenzene?
This negatively charged complex will be more stable in fluorobenzene as compared to chlorobenzene because of high -I effect of Fluorine. So due to stablisation of product intermediate reaction fluorobenzene is more reactive than chlorobenzene.
Why Fluorobenzene is more reactive than chlorobenzene?
It is the stronger resonance contribution from this effective electron donating resonance interaction with fluorine that makes fluorobenzene more reactive towards electrophilic aromatic substitution than chlorobenzene.
Is fluorine or chlorine more electron withdrawing?
Hence, halogens (fluorine, chlorine, etc) are electron withdrawing groups. Chlorine has the highest Electron Affinity in the periodic table (Even more than fluorine).
Which Halogen is most deactivating?
Halogens (F, Cl, Br, I) Are Deactivating Not all groups capable of pi donation are activating groups. For example, halogens (F, Cl, Br, I) tend to be deactivating.
Is OH or OCH3 a better leaving group?
This is why -OCH3 is a better leaving group, but it does not imply anything about the nucleophilicity. With your question, -OCH3 is a larger molecule (more electrons from the methyl donating group) and will more easily donate electrons (think kinetics), but it is also a weaker base than -OH.
