Is PH3 a Drago compound?
PH3 is regarded as a Drago molecule. For the pure ‘p’ orbitals that hold the electrons involved in bond formation, the bond angle is nearly 900.
What are Drago compounds?
Drago’s rule is an empirical rule and is used to explain the bond angles of hydrides of group 15 and 16 of or below 3rd period. So essentially it is only applicable for PH3, AsH3,SbH3 and H2S, H2Se, H2Te.
Is H2Te a Drago molecule?
H2S, H2Se, H2Te, H2Po. Yes, it is only strictly valid to P block elements and only to the compounds shown above which are specifically called as DRAGO’S COMPOUNDS. This rule is applicable to elements below 2nd period (i.e doesn’t include Nitrogen and Oxygen) and those which have Hydrogen exclusively as the side atom.
What is Dragon rule?
Drago rule states that , if – the central atom has at least one lone pair of electron on it. the central atom belongs to group 13,14 ,15 or 16 and is from 3rd to 7th period. if electronegativity of central element is 2.5 or less.
What geometry is PH3?
The geometry of PH3 is pyramidal.
Does AsH3 have sp3 hybridization?
Usually it is said that the hybridisation in AsH3 is sp3 (however this would imply a bond angle of 109.5- which is close to the ammonia angle)- however the angle of 91 0 is so close to the angle between the p orbitals (900)that it suggest there is no hybridisation at all, and that the As- H bonds involve only p …
What is hybridisation of N in NH3?
In Ammonia (NH3) or to be more precise the central atom in ammonia which is nitrogen is sp3 hybridized.
What is the name of this compound PH3?
PhosphanePhosphine / IUPAC ID
What is Drago’s rule in Inorganic Chemistry?
My textbooks states the Drago’s rule in inorganic chemistry as follows: The more electronegative atom prefers the orbital having more p character, and lone-pairs or less electronegative elements prefer such orbitals, as have more s character.
What is the molecular geometry of PH3?
Central atom has one lone pair. The electronegativity of the terminal atom is less than carbon. In essence, ph 3 is a Drago molecule and if we look at its bond angle data it shows that the p-orbitals have an angle of 90°. Looking at its Lewis structure we can state that molecular geometry of PH 3 is trigonal pyramidal.
What is the hybridization of P in PH3?
Important Points To Remember 1 In PH 3 hybridization does not take place. 2 The pure p orbitals take part in bonding. 3 In phosphine, orthogonal 3p orbitals overlap with 1s orbital of H.
What is the formula for C(CH3)3?
The C (CH3)3 is a wrong formula. Is not a complete molecule but a radical called “tert-butyl”: the single C atoms could be a radical (1 electron in the external orbital sp3) or an anion (2 electrons in the external orbital sp3) or a cation (zero electron in the external orbital sp3).
