Question

Depending upon Lewis structure\[O{F_2}\], \[{O_2}{F_2}\], and \[{S_2}{F_2}\] which of the following statement is incorrect?
A) \[{S_2}{F_2}\]has two isomeric structure, whereas \[{O_2}{F_2}\]has only one
B) The bond angle of \[O{F_2}\]is greater than \[OC{l_2}\]
C) The O-O bond angle in \[{O_2}{F_2}\]is smaller than \[{H_2}{O_2}\]
D) The O-F bond length in \[{O_2}{F_2}\]is larger than in \[O{F_2}\]

Answer 1

Hint:We have to draw all Lewis structure of given compounds. Then only we can find the incorrect statement. Also we have to draw isomeric structures of \[{S_2}{F_2}\]and\[{O_2}{F_2}\]to find out total possible structures.

Complete step-by-step answer:
As the Lewis structure is drawn we can easily assume that \[{O_2}{F_2}\]can have more than 1 isomeric structure. But\[{S_2}{F_2}\] has two isomeric structures, whereas \[{O_2}{F_2}\] has only one. Hence statement A is incorrect.
Also, the bond pair electrons in O-F are more towards F than the bond pair of electrons in O-H bond. The partial positive charge which is present on O atoms in \[{O_2}{F_2}\] is more than the partial positive charge which is present on O atoms in\[{H_2}{O_2}\]. Due to this, the bond pair of electrons of O-O bond in \[{O_2}{F_2}\] has more attraction than the bond pair of electrons of O-O bond in \[{H_2}{O_2}\].

Additional information:A Lewis structure can be drawn for any covalent molecule as well as coordination compounds.

Note:Lewis structure is also known as Lewis dot diagram or Lewis dot formula or Lewis dot structure or electron dot structure. LEDS (Lewis electron dot structure) is the representation that shows the bonding between different atoms of a molecule and the lone pair of an electron that may be present in a molecule. The Lewis structure was named after scientist Gilbert N. Lewis, who introduced it in the year 1916 in an article “The Atom and the Molecule.”
