What is the bond angle of pi3?

SiH4, an 8 valence electron system, is AB4; it has 109.5o bond angles. PI3, a 26 valence electron system, is AB3E; its bond angles are slightly less than 109.5o. BBr3, a 24 valence electron system, is AB3; it has 120o bond angles.

What is the central atom for PBr3?

Answer and Explanation: Phosphorous Tribromide (PBr3 P B r 3 ), the central atom is bonded to 3 Br atoms and one lone pair on the P atom. so, In PBr3 P B r 3 the hybridization is sp3 s p 3 .

How many electrons should helium he have around its Lewis dot diagram?

octet rule: Atoms try to achieve the electronic configuration of the noble gas nearest to them in the periodic table by achieving a full valence level with eight electrons. exceptions to the octet rule: Hydrogen (H) and helium (He) only need two electrons to have a full valence level.

How do you determine valence electrons?

Valence electrons can be found by determining the electronic configurations of elements. Thereafter the number of electrons in the outermost shell gives the total number of valence electrons in that element.

Why is PBr3 polar?

PBr3 is polar. Phosphorus has 5 electrons in its outer shell. It forms three single bonds with Br atoms, so PBr3 has three bonding pairs and one lone pair of electrons, the shape of the bonds is therefore trigonal pyramidal. Bromine is more electronegative than phosphorus so the P-Br bond is polar.

Which of the following is a correct Iupac name?

So the correct IUPAC name is 3-Ethyl-4,4-dimethylheptane. The structure of 3-Ethyl-4,4-dimethylheptane is, Options (B), (C) and (D) are incorrect as the naming is not done as per the IUPAC nomenclature of substituted alkanes. Therefore, the option (A) is correct.
