NITROGEN FAMILY (VII GROUP)

  Correct answer: (2)          CaCN₂ + Graphite. Here is some information regarding Nitrolim, Nitrolim (also known as nitrolime or lime nitrogen) is a nitrogenous fertilizer prepared by the cyanamide process. It is produced by passing nitrogen gas over heated calcium carbide (CaC₂) at high temperature (around 1000–1100°C). The reaction is: CaC₂ […]

Q 1: Nitrogen exhibits a maximum covalency of four. Explain.                    Since nitrogen is present in second period, it  has no vacant ‘d’ orbital (ie. 1s² 2s² 2p³). Hence, the excitation of 2s electron into 3s is not possible. Q 2 : What are the products obtained […]
