Question
In which of the molecules below is the carbon-carbon distance the longest? H_3C-CH_3 H_2C-CH_2 H-C = C-H H_2C = C-CH_2 H-C = C-Cl Of the molecules below, the bond in is the most polar. H_2 HAt HBr HCI HI As the number of covalent bonds between two atoms decreases, the distance between the atoms and the strength of the bond between them increases, increases decreases, decreases decreases, increases increases, decreases is unpredictable For resonance forms of a molecule or ion, the same atoms need not be bonded to each other in all resonance forms all the resonance structures are observed in various proportions there cannot be more than two resonance structures for a given species one always corresponds to the observed structure the observed structure is an average of the resonance forms of the ions below, only has a noble gas electron configuration. O^2+ Br^- S^3- I^+ K^- A valid Lewis structure of cannot be drawn without violating the octet rule. CO_2. NI_3 BrC1_5 SO_2 SiF_4 Of the following molecules, only is polar BF_3 Cl_2 BeC1_2. CBr_4 H_2S The molecular geometry of the right-most oxygen atom in the molecule below is bent trigonal planar T shapedExplanation / Answer
Hi
1) The CH3--CH3 has the the longest C-C distance, since it is has a single bond.
2) H-Cl has most polar since it has the highest electronegativity differnce among these.
3) Increases, Decreases; since the bond lengthis inversely proportional to number of covalent bonds and bond strength is directly proportional to number of covalent bonds.
4) The observed structure is an average of the resonance forms.
Thank you
