The diagram of Phosphine is studies based on the Lewis structure. Lewis structure is also called electron dot structures and is a picture to represent the lone pair of electrons and bonds with atoms or molecules. This can be grasped quickly using the following pointers:<\/p>\n<ul>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Phosphine lewis structure has 8 valence electrons.<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Since both N (Nitrogen) and P (Phosphorous) are present in the same group in the periodic table, the structure of PH3 is similar to NH3 (Ammonia).<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">However, the electro-negativity of Phosphorus is lesser than that of Nitrogen.<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">93.5 is the bond angle between H-P-H regions in the structure of Phosphine.<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">The bond length in P-H is 1.42 A.<\/p>\n<\/li>\n<\/ul>\n<p dir=\"ltr\">Phosphine is considered to be a Lewis base. This is due to the presence of a non-bonding electrons pair on the P shell which may be donated.<\/p>\n<h2 dir=\"ltr\"><span class=\"ez-toc-section\" id=\"Preparation_of_Phosphine\"><\/span>Preparation of Phosphine<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p dir=\"ltr\">The preparation of Phosphine gas begins by mixing dilute Hydrochloric Acid (HCl) or water with calcium phosphide (Ca3P2). The below formula represents this preparation.<\/p>\n<p dir=\"ltr\">Ca3P2 + 6H2O \u2192 3Ca(OH)2 + 2PH3<\/p>\n<p dir=\"ltr\">Ca3P2 + 6HCl \u2192 3CaCl2 + 2PH3<\/p>\n<p dir=\"ltr\">As you might have noticed, the other results along with Phosphine are Calcium Hydroxide (in the case of water) and Calcium Chloride (in the case of hydrochloric acid).<\/p>\n<p dir=\"ltr\">The laboratory preparation of Phosphine goes by the following case:<\/p>\n<p dir=\"ltr\">P4+3NaOH+3H2O \u2192 PH3 + 3NaH2PO2<\/p>\n<p dir=\"ltr\">Here, White Phosphorus has to be heated with concentrated Sodium Hydroxide to gove out Phosphine. Note that this preparation has to be undertaken in an inert atmosphere to make use of Carbon dioxide (CO2).<\/p>\n<p dir=\"ltr\">\n<h2 dir=\"ltr\"><span class=\"ez-toc-section\" id=\"Physical_and_chemical_properties_of_Phosphine\"><\/span>Physical and chemical properties of Phosphine<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3 dir=\"ltr\"><span class=\"ez-toc-section\" id=\"Physical_properties_of_Phosphine_are_given_below\"><\/span>Physical properties of Phosphine are given below:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Formula &#8211; PH3<\/p>\n<\/li>\n<li dir=\"ltr\">\n<p dir=\"ltr\" role=\"presentation\">Critical Temp.
