Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have an asymmetric geometry so that the bond dipoles do not cancel each other. Polar molecules interact through dipole–dipole intermolecular forces and hydrogen bonds. Brainly User Brainly User. In ethane (C2H6) BOnd angle is 109.5 in ethene(C2H4) bond angle is 120 in ethyne (C2H2) Bond angle is 180. MARK AS BRAINLIEST.

Ordering information is given on any current ... Fragments with higher molecular weights are expected to undergo further fragmentation to produce CHCO (m/z = 41), CH3CO (m/z =43), CO, the CH3-radical etc. The first two fragments are expected to decompose further to produce the CH3-group, CO, carbon and H2, or alternatively can form C2H2O (ketene), and CH3CHO (acetaldehyde).
Demonstrate an understanding of the terms bond length and bond angle and predict approximate bond angles in simple molecules and ions. I can state the shapes of BeCl2, BCl3, CH4, NH3, NH4+, H2O, CO2, gaseous PCl5 and SF6, as well as simple organic molecules listed in Unit 1 and Unit 2.There is a formation of a sigma bond and a pi bond between two carbon atoms. C2H4 Molecular Geometry And Bond Angles C2H4 molecular geometry is said to be planar in structure while the sp 2 orbitals are placed at a bond angle of 120 o .
The carbon-to-oxygen double bond is not shown but understood to be present. Because they contain the same functional group, aldehydes and ketones share many common properties, but they still differ enough to warrant their classification into two families.

Ans 3 : The molecular formula of C 3 H 6 O contains 2 less H atoms than propane (C 3 H 8) so that it must contain either a double bond or one ring. The combination of the double bond, ring and oxygen atoms means that the following functional groups are possible: aldehyde, alcohol, alkene, cycloalkane, epoxide, ether, ketone. to be at right angles to each other. If bonding occurs in this state, the 3 equivalent p electrons would form 3 equivalent bonds oriented at 90o to each other, and the s electron would form a bond of a different type and orientation from the other three. No such compound exists. The simplest hydrocarbon –methane (CH4)–

This makes the bond angle 109.5° ☛ Considering the measure of bond angles we find that the bond angle of water (H2O) is the least. ☛ WITHOUT CONSIDERING MEASURE OF BOND ANGLE This makes the bond angle 104.5°. NH3 forms a pyramidal structure due to presence of 1 lone pair.A ketene is an organic compound of the form R′R″C=C=O, where R and R' are two arbitrary monovalent chemical groups (or two separate substitution sites in the same molecule).
