Answer» Answer: For an atom to be sp-hybridized it MEANS that its s and p orbitals will combine and FORM new orbitals in order for the MOLECULAR geometry around this atom to be linear and the bond ANGLE equals 180∘ .29-Nov-2015Simple example of sp3 hybridization is ethane molecules. - In ethane, s,px,py and pz orbitals of both the carbon atoms undergo sp3 hybridization to give 4 hybrid orbitals with equal energy each. Among these orbitals, one hybrid orbitals of one carbon overlaps with 1s ORBITAL of hydrogen and gives 3 sigma bonds |

Why are the elements of groups IA and zero are called reactive elements and inert elements respectively? |
|
Answer» Answer: The ELEMENTS of GROUP 1A have 1 VALENCE electron in their last shell and hence can lose an electron easily during compound formation, making them very reactive. The elements of zero group have a stable electronic configuration with their last shell complete and hence do not react easily with other elements to ATTAIN stable electronic configuration. Therefore, they are inert. |

Define the following terms and give two examples each :-★ Anhydrous Salt★ Hydrated Salt★ Water of crystallisation★Deliquescent substances★Hygroscopic Substances★Efflorescent Salts |
|
Answer» Answer: 1. Anhydrous salt- A compound in which all water molecules are removed is called Anhydrous salt. EG- anhydrous copper sulphate(CuSO4) and anhydrous ferrous sulphate(FESO4) 2. Hydrated Salt- A compound with one or more chemically combined water molecule. EG- Copper sulphate pentahydrate (CuSO4.5H2O) and Ferrous sulphate(FeSO4.7H2O) 3. Water of crystallisation- Water of crystallization is the amount of water molecules which are PRESENT in one formula unit of salt. EG- PROTEINS with more than 50% of the water of crystallization and copper sulfate pentahydrate with five molecules of water of crystallization. 4. Deliquescent substance- The substances which absorb moisture from the atmosphere on exposure to air. By absorbing moisture they may dissolve in the water absorbed and change into solution. Such substances are called deliquescent substances. EG- Calcium chloride. 5. Hygroscopic substances- The substances which do not undergo any change in physical state on the absorption of moisture from the atmospheric air. These are called hygroscopic substance. EG- Calcium oxide, cobalt chloride 6.Effloroscent salts- The salts which lose water of crystallization either completely of PARTIALLY on exposure to atmospheric air are called efflorescent substances. EG- Na2CO3.10H2O loses nine water molecules on exposure to air and the remaining one water molecule on heating. |
