  Monogamy relations place restrictions on the shareability of quantum
corellations in multipartite states. Being an intrinsic quantum feature,
monogamy property throws light on {\emph{residual}} entanglement, an
entanglement which is not accounted for by the pairwise entanglement in the
state. Expressed in terms of suitable pairwise entanglement measures such as
concurrence, the monogamy inequality leads to the evaluation of
{\emph{tangle}}, a measure of residual entanglement. In this work, we explore
monogamy relations in pure symmetric multiqubit states constituted by two
distinct spinors, the so-called {\emph{Dicke-class}} of states. Pure symmetric
$N$-qubit states constituted by permutation of two orthogonal qubits form the
well-known Dicke states. Those $N$-qubit pure symmetric states constructed by
permutations of two non-orthogonal qubits are a one-parameter class of
generalized Dicke states. With the help of Majorana geometric representation
and angular momentum algebra, we analyze the bounds on monogamy inequality,
expressed in terms of squared concurrence/squared negativity of partial
transpose. We show that the states with equal distribution of the two spinors
are more monogamous and hence possess larger residual entanglement when
compared to other inequivalent classes with different degeneracy
configurations.
