- Why is the H–N–H angle in NH3 smaller than the H–C–H bond angle in CH4? Why is the H–N–H angle in NH4 + identical to the H–C–H bond angle in CH4?arrow_forwardIn H2C=NH, what form of orbital retains the lone pair of electrons on nitrogen?arrow_forward2a) The molecule ethene (or ethylene), which has the molecular formula C₂H4, contains two carbon atoms with planar geometry. Construct a model of ethene by first connecting two black balls with two springs. Use four short sticks and four yellow balls to complete the structure. Sketch a perspective representation (a three dimensional drawing) of the structure. 2b) What is the C=C-H bond angle in ethene?arrow_forward
- Which has a greater dipole moment? CH2Cl2 or CH2F2 The book states that a C-Cl bond has a greater dipole moment than a C-F bond, regardless of F's larger electronegativity, because the C-Cl has a larger bond length. Does the same logic apply?arrow_forwardExplain why HCl has a smaller dipole moment than HF, even though the H¬Cl bond is longer than the H¬F bond?arrow_forwardPart A Benzene is an organic chemical compound with the molecular formula C6H6. In the benzene molecule, carbon atoms form a ring with alternating single and double bonds connecting them. Thus, each individual carbon atom forms one o bond with another carbon atom and one o and one bond with another carbon atom. Each carbon atom also forms one o bond with a hydrogen atom.
