    Question 3 0 / 1 pts Based on the Lewis Structure for PH2Br, what is its electronic geometry? Tetrahedral Trigonal planar Linear Question 4 0 / 1 pts Based on the Lewis Structure for PH2Br, what is its molecular geometry? ›

    Answer & Explanation

    What is the Vsepr shape of CH2Br2? ›

    The structure shows two bromine atoms and two hydrogen atoms singly-bonded to a central oxygen atom. Each bromine atom has three lone pairs. Based on the Lewis structure, the molecular geometry of C H X 2 B r X 2 \ce{CH2Br2} CHX2​BrX2​ is tetrahedral because it has four bonding groups.

    What is the molecular geometry of a tetrahedral molecule? ›

    In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron. The bond angles are cos1(−1⁄3) = 109.4712206... ° ≈ 109.5° when all four substituents are the same, as in methane (CH 4) as well as its heavier analogues.

    Is SF2 bent or tetrahedral? ›

    SF2 would have a structure analogous to that of water — the central atom (S in SF2) has two lone pairs and two single bonds. Thus, the orbitals would be in a tetrahedral arrangement and the molecule would be bent. The ideal angle for a tetrahedron is 109.5 deg.

    Is CH2Br2 tetrahedral? ›

    Expert-Verified Answer

    CH2Br2 (Dibromomethane) has a tetrahedral molecular geometry with bond angles of approximately 109.5 degrees.

    What is the shape of becl2 using the VSEPR model? ›

    During the formation of , the beryllium atom is covalently bonded with two chlorine atoms. In this molecule, there are two bond pairs while no lone pair is found in the molecule. The hybridization of is hybridization. Thus, as per VSEPR theory, the shape of is linear.

    What does vsepr stand for? ›

    VSEPR is an acronym that stands for valence shell electron pair repulsion. The model was proposed by Nevil Sidgwick and Herbert Powell in 1940. Ronald Gillespie and Ronald Nyholm then developed the model into their theory published in 1957; they are considered the developers of the VSEPR theory.

    Which has a tetrahedral shape? ›

    There are many common molecules with a tetrahedral shape. Some of these molecules include methane (CH4), phosphate (PO4), sulfate (SO4), permanganate (MnO4) and ammonium (NO4).

    Is tetrahedral trigonal planar? ›

    If a molecule has 3 bonds and 0 lone pairs, it is trigonal planar. If a molecule has 3 bonds and 1 lone pair, it is bent or angular. If a molecule has 4 bonds and 0 lone pairs, it is tetrahedral.

    What is the Lewis Vsepr structure? ›

    Lewis-structure diagrams are used to identify valence electrons in polyatomic molecules, and the VSEPR model is used to understand how these valence electrons are arranged in three-dimensional space. The VSEPR model assumes that there will always be electrostatic repulsion between pairs of valence electrons.

    What type of compound is CH2Br2? ›

    Dibromomethane or methylene bromide, or methylene dibromide is a halomethane with the formula CH2Br2.

    Is CH2Br2 a dipole? ›

    Re: Polar or nonpolar? CH2BR2 is a polar molecule because its dipole moments do not cancel out so it has a non-zero net moment.

    What is the bond angle of SF2 shape? ›

    Answer and Explanation:

    The given compound is S F 2 . In this compound, sulfur is bonded with two fluorine atoms by single bonds. There is a presence of two lone pair of electrons on sulfur atom which is present at the centre. The bond angle is around 98.3 degrees.
