(a)
Interpretation:
The logic should be explained for the suggestion of similar structure of
Concept Introduction:
The electrons present in the outermost energy level or shell is known as valence electrons. These electrons are available for bonding and outermost shell is known as valence shell.
(b)
Interpretation:
The most symmetric pattern of carbon, boron and nitrogen atoms in
Concept Introduction:
Fullerene molecular formula:
Fullerene has 60 carbon atoms and its structure is arranged in a closed net having 12 pentagonal and 12 hexagonal faces to form cage like structure.

- Cinnamaldehyde ocaus naturally in cinnamon oil. (a) What is the most polar bond in the molecule? (b) How many bonds and how many bonds are there? (c) Is cis-trans isomerism possible? If so, draw the isomers of the molecule. (d) Give the hybridization of the C atoms in the molecule. (e) What are the values of the bond angles 1, 2, and 3 ?arrow_forwardThe sulfamate ion, H2NSO3, can be thought of as having been formed from the amide ion, NH2, and sulphur trioxide, SO3. (a) What are the electron-pair and molecular geometries or the amide ion and or SO3? What are the hybridizations of the N and S atoms, respectively? (b) Sketch a structure for the sulfamate ion, and estimate the bond angles. (c) What changes in hybridization do you expect for N and S in the course of the reaction NH2 + SO3 H2NSO3? (d) Is SO3 the donor of an electron pair or the acceptor of an electron pair in the reaction with amide ion? Does the electrostatic potential map shown below confirm your prediction?arrow_forwardAcetic acid, the sour constituent of vinegar, has the following structure: Indicate what geometry iiv is expected to be found about each of the atoms labeled a, b, and c.arrow_forward
- For the following descriptions of molecules, draw the Lewis structure (showing all atoms, lone pairs, formal changes) of the molecule and show all bond angles (assuming ideal VSEPR angles) 1) An organic compound with the molecular formula H3CNO2. C is sp2 hybridized, N is sp3 hybridized, one O is sp2 hybridized, while the second O is sp3 hybridized.arrow_forwardWhat are the bond angles around heteroatoms and non-sp3 hybridised C atoms in C14H23NO ?arrow_forwardExplain why the molecules with central atoms in period 2 do not follow a similar trend for lines representing Groups 15, 16 and 17arrow_forward
- Octahedral molecules only have a single bond angle - write down its value. What angle do both the square pyramid and square planar structures contain?The trigonal planar (1) and trigonal pyramid (4) structures both contain 4 (1 central and 3 apical) atoms. From the models you have created and drawn, are these two structures the same? If they are not, identify the key angles which distinguish these two structures.arrow_forwardPick the pair of possible bond angles in the Lewis structure below. a-90 or 180 b-109 or 120 c-109 or 120 d-120 or 180 e-90 or 120 f-109 or 180arrow_forwardWhy is CH4 tetrahedral but XeF4 square planar?arrow_forward
