In 1904, Schur proved that if the center of a group G has finite index, then the drived subgroup,
G′ is also finite. The Lie algebra analogue of Schur’s theorem is well-known. In 1994, Moneyhun
howed that if L is a Lie algebra such that dim (L/Z(L)) = n, then dim (L^2) < 1/2n(n−1).The first
author and F. Saeedi investigated the converse of Moneyhun’s theorem under some conditions.
In this paper, we will extend their results
