The substituted hydrocarbon is a hydrocarbon with one or more of hydrogen is substituted with other element, (every so often a halogen like as bromine or chlorine) or other group of atoms as -OH. Such as: - The simple hydrocarbon is methane (CH4). Substitute chlorine for the hydrogen to get Methyl Chloride (CH3Cl) is used for cleaning. Sub to get- Methylene Chloride (CH2Cl2) is used as a paint stripper. Sub to get- Chloroform (CHCl3) is an antique anaesthetic. Sub to get- Carbon Tetrachloride (CCl4) is used in the fire extinguishers and cleaning. Substitute single -OH group into the - CH4 to get methanol (CH3OH) or into C2H6 to get ethanol (C2H5OH) The above instances all begin with the unbranched non-cyclic hydrocarbons, but any hydrocarbon is an appropriate target. A known instance is a double replacement of chlorine at the opposite ends of the benzene ring to form paradichlorbenzene, normally found hanging in toilet bowls. C6H6 becomes C6H4Cl2
4) The addition of S2- ion to Fe(OH)2(s). Explain why the addition of S2- ion to Cr(OH)3(s) does not result in the formation of Cr2S3(s).
Choose the right answer from following. If P and P are the vapour pressure of a solvent and its solution respectively N1 and N2 and are the mole fractions of the solvent and solute respectively, then correct relation is: (a) P= PoN1 (b) P= Po N2 (c)P0= N2 (d)
Certain sols have the property of setting to a semi-solid, jelly-like form by enclosing the entire amount of liquid within itself when they are present at high concentrations. This process is called gelation and colloidal systems with jelly-like appearance are known as gels. Some common examples
37% weight of HCl and density is 1.1g/ml. find molarity of HCl
These types of polymers are formed as a result of condensation reaction between monomer units. Some common examples are being discussed here: 1. Polyesters Q : Explain the molecular mass with respect During the formation of polymers, different macromolecules have different degree of polymerisation i.e. they have varied chain lengths. Thus, the molecular masses of the individual macromolecules in a particular sample of the polymer are different. Hence, an average value of the molecular mass is

The ionic radii of Rb+ and I- respectively are 1.46 Å and 2.16Å. The very most probable type of structure exhibited by it is: (a) CsCl type (b) ZnS type (c) Nacl type (d) CaF2 type Q : What are the various types of drugs Drugs are broadly classified into following types depending on the purpose for which they are used. 1. Antipyretics
