Pseudophryne. The corroboree frog is incredibly distinctive with its bright yellow and black striped skin. The upper surface has a rough texture whilst the belly is smooth and either black and yellow or black and white.Females are larger in size than males and, unusually, neither sex has webbed toes.seudophryne.

(b) P4 is non polar covalent. (c) BF3 is non polar covalent molecule (individual B-F bonds are polar but the net dipole moment is zero due to its triangular planar geometry).b) P4 is non polar covalent. (c) BF3 is non polar covalent molecule (individual B-F bonds are polar but the net dipole moment is zero due to its triangular planar geometry).
(2) S-Br bond is the most polar. GROUP D: Si-Cl bond is the most polar. GROUP -E : because of the presence of hydrogen,the P-block elements take up a negative charge and act as an anion. thus according to the rule , Sn-H bond is the most polar. GROUP - F : here the P-Block elements act as a cation. So smaller the size ,grater the polarity.as aluminium is the smallest among the given, Al-Br bond is the most polar. Please refer to the periodic table for any doubts in the position of the elements. muruganandam p Â· 10 years ago
