Which of the following is 4-bromopent-2-ene?
CH3-CH=CH-CH(Br)-CH3 is 4-bromopent-2-ene. [ According to priority order of functional groups =( double bond) comes before than that of halo (Br) group ]
Metallic radii of some transition elements are given below. Which of these elements will have the highest density?
On moving left to right along period, metallic radius decreases while mass increases. Decrease in metallic radius coupled with increase in atomic mass results in increase in density of metal.
Hence, among the given four choices Cu belongs to right side of Periodic Table in transition metal, and. it has highest density (89 g/cm3).
The isomer of dichlorobenzene which has highest melting point:
p-Dichlorobenzene has higher melting point then o and m isomers because it is more symmetric in structure and fits perfectly in crystal lattice.
Although haloalkane are polar in nature, yet they are slightly soluble in water. Which characteristic behavior is responsible for such kind of property?
Haloalkanes although polar in nature are insoluble in water because they are not able to form hydrogen bonds with water molecules.
Which of the following is a tertiary halogenoalkanes?
√Br CH3 -( CH )- CH2 - CH2 - CH3 √CH3 The carbon with which the Br is bonded is bonded with another 3 carbon atoms. So haloalkane is 3.
Which of the following is not true about optical isomers?
Superimposable (mirror images of each other) substances are achiral because chiral substances cannot have its own mirror image. And achiral substances do not show optical activity nor any optical isomers. Hence, answer is B.
Which of the following is not an aryl halide?
Because it is Open chain compound /Aliphatic Compound and not aryl halide as it does not contain halogen atom. It's simply alkane.
Pick up the correct statement about alkyl halides.
In general organic compounds are soluble in organic solvents. Hence alkyl halides are soluble in organic solvents.
Which one of the following is 1-bromo-3-methyl butane?
It is 1-bromo-3-methylbutane.
C5H11Br is least soluble in:
C5H11Br are only very slightly soluble in water. They are more soluble in organic solvents.
